Pastry refers to a variety of doughs (often enriched with fat or eggs), as well as the sweet and savoury baked goods made from them. These goods are often called pastries as a synecdoche , and the dough may be accordingly called pastry dough for clarity. Sweetened pastries are often described as bakers' confectionery . Common pastry dishes include pies , tarts , quiches , croissants , and pasties .
101-652: A pasty ( / ˈ p æ s t i / ) or Cornish pasty is a British baked pastry , a variety of which is particularly associated with Cornwall , but has spread all over the British Isles , and elsewhere through the Cornish diaspora . It consists of an uncooked filling, typically meat and vegetables, baked in a folded and crimped shortcrust pastry circle. The traditional Cornish pasty, which since 2011 has had Protected Geographical Indication (PGI) status in Europe,
202-519: A direct bandgap , and can be used in laser diodes and LEDs to convert electrical energy directly into light. After World War I , the United States built a stockpile of 20,000 tons of weaponized lewisite (ClCH=CHAsCl 2 ), an organoarsenic vesicant (blister agent) and lung irritant. The stockpile was neutralized with bleach and dumped into the Gulf of Mexico in the 1950s. During
303-568: A tetrahedral structure in which each atom is bound to each of the other three atoms by a single bond. This unstable allotrope, being molecular, is the most volatile, least dense, and most toxic. Solid yellow arsenic is produced by rapid cooling of arsenic vapor, As 4 . It is rapidly transformed into grey arsenic by light. The yellow form has a density of 1.97 g/cm . Black arsenic is similar in structure to black phosphorus . Black arsenic can also be formed by cooling vapor at around 100–220 °C and by crystallization of amorphous arsenic in
404-554: A wood preservative . In the 1930s, a process of treating wood with chromated copper arsenate (also known as CCA or Tanalith ) was invented, and for decades, this treatment was the most extensive industrial use of arsenic. An increased appreciation of the toxicity of arsenic led to a ban of CCA in consumer products in 2004, initiated by the European Union and United States. However, CCA remains in heavy use in other countries (such as on Malaysian rubber plantations). Arsenic
505-612: A "Cornish pasty" that was smaller and was to be eaten as an "economical savoury nibble for polite middle-class Victorians". On 20 July 2011, after a nine-year campaign by the Cornish Pasty Association (CPA) – the trade organisation of about 50 pasty makers based in Cornwall – the name "Cornish pasty" was awarded Protected Geographical Indication (PGI) status by the European Commission . According to
606-410: A 13th-century charter that was granted by King John of England (in 1208) to the town of Great Yarmouth . The town was bound to send to the sheriffs of Norwich every year one hundred herrings, baked in twenty four pasties , which the sheriffs delivered to the lord of the manor of East Carlton who then conveyed them to the king. Around the same time, 13th-century chronicler Matthew Paris wrote of
707-562: A delicate texture, often flaky or crumbly, and rich flavor —simple breads are thus excluded from the pastry category. Pastries also tend to be baked. The European tradition of pastry-making is often traced back to the shortcrust era of flaky doughs that were in use throughout the Mediterranean in ancient times. In the ancient Mediterranean, the Romans, Greeks, and Phoenicians all had filo-style pastries in their culinary traditions. In
808-490: A distorted octahedral complex, with the three atoms in the same double-layer being slightly closer than the three atoms in the next. This relatively close packing leads to a high density of 5.73 g/cm . Grey arsenic is a semimetal , but becomes a semiconductor with a bandgap of 1.2–1.4 eV if amorphized . Grey arsenic is also the most stable form. Yellow arsenic is soft and waxy, and somewhat similar to tetraphosphorus ( P 4 ). Both have four atoms arranged in
909-614: A good pastry because they used oil in the cooking process, and oil causes the pastry to lose its stiffness. In the medieval cuisine of Northern Europe , pastry chefs were able to produce nice, stiff pastries because they cooked with shortening and butter. Some incomplete lists of ingredients have been found in medieval cookbooks, but no full, detailed versions. There were stiff, empty pastries called coffins or ' huff paste ', that were eaten by servants only and included an egg yolk glaze to help make them more enjoyable to consume. Medieval pastries also included small tarts to add richness. It
1010-484: A letter from a baker to Henry VIII 's third wife Jane Seymour confirms: "...hope this pasty reaches you in better condition than the last one ..." In his diaries written in the mid-17th century, Samuel Pepys makes several references to his consumption of pasties, for instance "dined at Sir W. Pen's ... on a damned venison pasty, that stunk like a devil", but after this period the use of the word outside Devon and Cornwall declined. In contrast to its earlier place amongst
1111-400: A lot of time and focus. Presentation is an important aspect of pastry and dessert preparation. The job is often physically demanding, requiring attention to detail and long hours. Pastry chefs are also responsible for creating new recipes to put on the menu, and they work in restaurants, bistros, large hotels, casinos and bakeries. Pastry baking is usually done in an area slightly separate from

Using unclarified butter does not work well because of its water content; clarified butter , or ghee , which is virtually water-free, is better, but shortcrust pastry using only butter may develop an inferior texture. If the fat is melted with hot water or if liquid oil
1313-461: A luxurious or sweet product. This meaning still persisted in the nineteenth century, though by then the term more often referred to the sweet and often ornate confections implied today. The precise definition of the term pastry varies based on location and culture. Common doughs used to make pastries include filo dough , puff pastry , choux pastry , short dough , pâte brisée , pâte sucrée , and other enriched doughs. Pastries tend to have
1414-517: A major source of arsenic contamination of groundwater in regions with high levels of naturally-occurring arsenic minerals. Synthetic arsenates include Scheele's Green (cupric hydrogen arsenate, acidic copper arsenate), calcium arsenate , and lead hydrogen arsenate . These three have been used as agricultural insecticides and poisons . The protonation steps between the arsenate and arsenic acid are similar to those between phosphate and phosphoric acid . Unlike phosphorous acid , arsenous acid
1515-454: A pattern for Cornish pasties in quite another part of the country. Cornish pasties are very popular with the working classes in this neighbourhood, and have lately been successfully introduced into some parts of Devonshire. They are made of small pieces of beef, and thin slices of potato, highly peppered, and enclosed in wrappers of paste. By the late 19th century, national cookery schools began to teach their pupils to create their own version of
1616-445: A pie, filled with venison , salmon or other meat, vegetables or cheese, baked without a dish. Pasties have been mentioned in cookbooks throughout the ages. For example, the earliest version of Le Viandier (Old French) has been dated to c. 1300 and contains several pasty recipes. In 1393, Le Menagier de Paris contains recipes for pasté with venison, veal , beef, or mutton . Other early references to pasties include
1717-483: A pure elemental crystal . It has various allotropes , but only the grey form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition ). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III–V compound semiconductor gallium arsenide . Arsenic and its compounds, especially
1818-1050: A regular savory dim sum menu item. In the 19th century, the British brought western-style pastry to the Far East , though it would be the French-influenced Maxim in the 1950s that made western pastry popular in Chinese-speaking regions starting with Hong Kong . The term "western cake" (西餅) is used to refer to western pastry, otherwise Chinese pastry is assumed. Other Asian countries such as Korea prepare traditional pastry-confections such as tteok , hangwa , and yaksik with flour, rice, fruits, and regional specific ingredients to make unique desserts. Japan also has specialized pastry-confections better known as mochi and manjū . Pastry-confections that originate in Asia are clearly distinct from those that originate in
1919-532: A role in human metabolism. However, arsenic poisoning occurs in multicellular life if quantities are larger than needed. Arsenic contamination of groundwater is a problem that affects millions of people across the world. The United States' Environmental Protection Agency states that all forms of arsenic are a serious risk to human health. The United States' Agency for Toxic Substances and Disease Registry ranked arsenic number 1 in its 2001 prioritized list of hazardous substances at Superfund sites. Arsenic
2020-427: A shovel over a candle. Side-crimped pasties gave rise to the suggestion that the miner might have eaten the pasty holding the thick edge of pastry, which was later discarded, thereby ensuring that dirty fingers (possibly including traces of arsenic ) did not touch the food or mouth. However, many old photographs show that pasties were wrapped in bags made of paper or muslin and were eaten from end to end; according to
2121-448: A spoonful of clotted cream . Whilst the PGI rules state that a Cornish pasty must be a "D" shape, with crimping along the curve (i.e., side-crimped), crimping is variable within both Devon and Cornwall, with some advocating a side crimp while others maintain that a top crimp is more authentic. Some sources state that the difference between a Devon and a Cornish pasty is that a Devon pasty has

#17327918094862222-591: A subsidiary of Pfizer Inc., which produces roxarsone, voluntarily suspended sales of the drug in response to studies showing elevated levels of inorganic arsenic, a carcinogen, in treated chickens. A successor to Alpharma, Zoetis , continued to sell nitarsone until 2015, primarily for use in turkeys. During the 17th, 18th, and 19th centuries, a number of arsenic compounds were used as medicines, including arsphenamine (by Paul Ehrlich ) and arsenic trioxide (by Thomas Fowler ), for treating diseases such as cancer or psoriasis . Arsphenamine, as well as neosalvarsan ,
2323-717: A top-crimp and is oval in shape, whereas the Cornish pasty is semicircular and side-crimped along the curve. However, pasties with a top crimp have been made in Cornwall for generations, yet those Cornish bakers who favour this method now find that they cannot legally call their pasties "Cornish". Paul Hollywood , writing for BBC Food , stated that a traditional Cornish pasty should have about 20 crimps. Migrating Devonian and Cornish miners and their families (colloquially known as Cousin Jacks and Cousin Jennies) helped to spread pasties into
2424-415: A version of photosynthesis in the absence of oxygen with arsenites as electron donors , producing arsenates (just as ordinary photosynthesis uses water as electron donor, producing molecular oxygen). Researchers conjecture that, over the course of history, these photosynthesizing organisms produced the arsenates that allowed the arsenate-reducing bacteria to thrive. One strain , PHS-1, has been isolated and
2525-417: Is a common practice among those cottagers who bake at home of making little pasties for the dinners of those who may be working at a distance in the fields. They will last the whole week, and are made of any kind of meat or fruit, rolled up in a paste made of flour and suet or lard. A couple of ounces of bacon and half a-pound of raw potatoes, both thinly sliced and slightly seasoned, will be found sufficient for
2626-458: Is classified as a Group-A carcinogen . The three most common arsenic allotropes are grey, yellow, and black arsenic, with grey being the most common. Grey arsenic (α-As, space group R 3 m No. 166) adopts a double-layered structure consisting of many interlocked, ruffled, six-membered rings. Because of weak bonding between the layers, grey arsenic is brittle and has a relatively low Mohs hardness of 3.5. Nearest and next-nearest neighbors form
2727-606: Is estimated that approximately 57 million people in the Bengal basin are drinking groundwater with arsenic concentrations elevated above the World Health Organization 's standard of 10 parts per billion (ppb). However, a study of cancer rates in Taiwan suggested that significant increases in cancer mortality appear only at levels above 150 ppb. The arsenic in the groundwater is of natural origin, and
2828-531: Is filled with beef , sliced or diced potato, swede (also known as yellow turnip or rutabaga – referred to in Cornwall and other parts of the West Country as turnip ) and onion, seasoned with salt and pepper, and baked . Today, the pasty is the food most associated with Cornwall. It is a traditional dish and accounts for 6% of the Cornish food economy. Pasties with many different fillings are made, and some shops specialise in selling pasties. The origins of
2929-438: Is generally skirt steak . Swede is sometimes called turnip in Cornwall, but the recipe requires use of actual swede, not turnip. Pasty ingredients are usually seasoned with salt and pepper, depending on individual taste. The use of carrot in a traditional Cornish pasty is frowned upon, though it does appear regularly in recipes. The type of pastry used is not defined, as long as it is golden in colour and will not crack during
3030-514: Is genuinely tribasic, with the formula As(OH) 3 . A broad variety of sulfur compounds of arsenic are known. Orpiment ( As 2 S 3 ) and realgar ( As 4 S 4 ) are somewhat abundant and were formerly used as painting pigments. In As 4 S 10 , arsenic has a formal oxidation state of +2 in As 4 S 4 which features As-As bonds so that the total covalency of As is still 3. Both orpiment and realgar, as well as As 4 S 3 , have selenium analogs;
3131-589: Is in alloying with lead. Lead components in car batteries are strengthened by the presence of a very small percentage of arsenic. Dezincification of brass (a copper-zinc alloy) is greatly reduced by the addition of arsenic. "Phosphorus Deoxidized Arsenical Copper" with an arsenic content of 0.3% has an increased corrosion stability in certain environments. Gallium arsenide is an important semiconductor material, used in integrated circuits . Circuits made from GaAs are much faster (but also much more expensive) than those made from silicon . Unlike silicon, GaAs has

3232-647: Is inhalation of atmospheric gases and dusts. During the Victorian era , arsenic was widely used in home decor, especially wallpapers. In Europe, an analysis based on 20,000 soil samples across all 28 countries show that 98% of sampled soils have concentrations less than 20 mg kg-1. In addition, the As hotspots are related to frequent fertilization and close distance to mining activities. Extensive arsenic contamination of groundwater has led to widespread arsenic poisoning in Bangladesh and neighboring countries. It
3333-427: Is little danger in eating fish because this arsenic compound is nearly non-toxic. Naturally occurring sources of human exposure include volcanic ash , weathering of minerals and ores, and mineralized groundwater. Arsenic is also found in food, water, soil, and air. Arsenic is absorbed by all plants, but is more concentrated in leafy vegetables, rice, apple and grape juice, and seafood. An additional route of exposure

Pastry The French word pâtisserie is also used in English (with or without the accent) for many of the same foods, as well as the set of techniques used to make them. Originally, the French word pastisserie referred to anything, such as a meat pie, made in dough ( paste , later pâte ) and not typically
3535-433: Is recovered primarily from copper refinement dust. On roasting arsenopyrite in air, arsenic sublimes as arsenic(III) oxide leaving iron oxides, while roasting without air results in the production of gray arsenic. Further purification from sulfur and other chalcogens is achieved by sublimation in vacuum, in a hydrogen atmosphere, or by distillation from molten lead-arsenic mixture. The word arsenic has its origin in
3636-561: Is related to the gammaproteobacterium Ectothiorhodospira shaposhnikovii . The mechanism is unknown, but an encoded Arr enzyme may function in reverse to its known homologues . In 2011, it was postulated that the Halomonadaceae strain GFAJ-1 could be grown in the absence of phosphorus if that element were substituted with arsenic, exploiting the fact that the arsenate and phosphate anions are similar structurally. The study
3737-467: Is released from the sediment into the groundwater, caused by the anoxic conditions of the subsurface. This groundwater was used after local and western NGOs and the Bangladeshi government undertook a massive shallow tube well drinking-water program in the late twentieth century. This program was designed to prevent drinking of bacteria-contaminated surface waters, but failed to test for arsenic in
3838-474: Is resistant to all-trans retinoic acid . A 2008 paper reports success in locating tumors using arsenic-74 (a positron emitter). This isotope produces clearer PET scan images than the previous radioactive agent, iodine -124, because the body tends to transport iodine to the thyroid gland producing signal noise. Nanoparticles of arsenic have shown ability to kill cancer cells with lesser cytotoxicity than other arsenic formulations. The main use of arsenic

The valence electron count of GaAs is the same as a pair of Si atoms, but the band structure is completely different which results in distinct bulk properties. Other arsenic alloys include
4040-490: Is the 22nd most abundant element in seawater and ranks 41st in abundance in the universe. Minerals with the formula MAsS and MAs 2 (M = Fe , Ni , Co ) are the dominant commercial sources of arsenic, together with realgar (an arsenic sulfide mineral) and native (elemental) arsenic. An illustrative mineral is arsenopyrite ( Fe As S ), which is structurally related to iron pyrite . Many minor As-containing minerals are known. Arsenic also occurs in various organic forms in
4141-485: Is therefore called a monoisotopic element . As of 2024, at least 32 radioisotopes have also been synthesized, ranging in atomic mass from 64 to 95. The most stable of these is As with a half-life of 80.30 days. All other isotopes have half-lives of under one day, with the exception of As ( t 1/2 =65.30 hours), As ( t 1/2 =26.0 hours), As ( t 1/2 =17.77 days), As ( t 1/2 =26.26 hours), and As ( t 1/2 =38.83 hours). Isotopes that are lighter than

4242-496: Is typically pyramidal owing to the influence of the lone pair of electrons . One of the simplest arsenic compounds is the trihydride, the highly toxic, flammable, pyrophoric arsine (AsH 3 ). This compound is generally regarded as stable, since at room temperature it decomposes only slowly. At temperatures of 250–300 °C decomposition to arsenic and hydrogen is rapid. Several factors, such as humidity , presence of light and certain catalysts (namely aluminium) facilitate
4343-455: Is used to detect precise levels of intracellular arsenic and other arsenic bases involved in epigenetic modification of DNA. Studies investigating arsenic as an epigenetic factor can be used to develop precise biomarkers of exposure and susceptibility. The Chinese brake fern ( Pteris vittata ) hyperaccumulates arsenic from the soil into its leaves and has a proposed use in phytoremediation . Inorganic arsenic and its compounds, upon entering

A good pastry is light and airy and fatty, but firm enough to support the weight of the filling. When making a shortcrust pastry , care must be taken to blend the fat and flour thoroughly before adding any liquid---to ensure that the flour granules are adequately coated with fat and less likely to develop gluten . On
4545-712: The Renaissance era . During the Bronze Age , arsenic was melted with copper to make arsenical bronze . Jabir ibn Hayyan described the isolation of arsenic before 815 AD. Albertus Magnus (Albert the Great, 1193–1280) later isolated the element from a compound in 1250, by heating soap together with arsenic trisulfide . In 1649, Johann Schröder published two ways of preparing arsenic. Crystals of elemental (native) arsenic are found in nature, although rarely. Cadet's fuming liquid (impure cacodyl ), often claimed as

It was adopted into Greek (using folk etymology ) as arsenikon ( ἀρσενικόν ) – a neuter form of the Greek adjective arsenikos ( ἀρσενικός ), meaning "male", "virile". Latin -speakers adopted
4747-631: The Vietnam War , the United States used Agent Blue , a mixture of sodium cacodylate and its acid form, as one of the rainbow herbicides to deprive North Vietnamese soldiers of foliage cover and rice. Some species of bacteria obtain their energy in the absence of oxygen by oxidizing various fuels while reducing arsenate to arsenite. Under oxidative environmental conditions some bacteria use arsenite as fuel, which they oxidize to arsenate. The enzymes involved are known as arsenate reductases (Arr). In 2008, bacteria were discovered that employ

The organic compound arsenobetaine is found in some marine foods such as fish and algae, and also in mushrooms in larger concentrations. The average person's intake is about 10–50 μg/day. Values about 1000 μg are not unusual following consumption of fish or mushrooms, but there
4949-457: The nonmetals . Though stable in dry air, arsenic forms a golden-bronze tarnish upon exposure to humidity which eventually becomes a black surface layer. When heated in air, arsenic oxidizes to arsenic trioxide ; the fumes from this reaction have an odor resembling garlic. This odor can be detected on striking arsenide minerals such as arsenopyrite with a hammer. It burns in oxygen to form arsenic trioxide and arsenic pentoxide , which have
5050-542: The 20th century. A 2006 study of the remains of the Australian racehorse Phar Lap determined that its 1932 death was caused by a massive overdose of arsenic. Sydney veterinarian Percy Sykes stated, "In those days, arsenic was quite a common tonic, usually given in the form of a solution ( Fowler's Solution ) ... It was so common that I'd reckon 90 per cent of the horses had arsenic in their system." The toxicity of arsenic to insects, bacteria, and fungi led to its use as
5151-521: The As ion as the formation of such an anion would be highly endothermic and even the group 1 arsenides have properties of intermetallic compounds. Like germanium , selenium , and bromine , which like arsenic succeed the 3d transition series , arsenic is much less stable in the +5 oxidation state than its vertical neighbors phosphorus and antimony , and hence arsenic pentoxide and arsenic acid are potent oxidizers . Compounds of arsenic resemble, in some respects, those of phosphorus , which occupies

#17327918094865252-444: The Greek term as arsenicum , which in French ultimately became arsenic , whence the English word "arsenic". Arsenic sulfides (orpiment, realgar ) and oxides have been known and used since ancient times. Zosimos ( c. 300 AD ) describes roasting sandarach (realgar) to obtain cloud of arsenic ( arsenic trioxide ), which he then reduces to gray arsenic. As the symptoms of arsenic poisoning are not very specific,

Many culinary historians consider French pastry chef Antonin Carême (1784–1833) to have been the first great master of pastry making in modern times. Pastry-making has a strong tradition in many parts of Asia. Chinese pastry is made from rice, or different types of flour, with fruit, sweet bean paste or sesame -based fillings. The mooncakes are part of Chinese Mid Autumn Festival traditions, while cha siu bao , steamed or baked pork buns, are

Its ingredients should include beef, swede (called turnip in Cornwall), potato and onion, with a light seasoning of salt and pepper, keeping a chunky texture. The pastry should be golden and retain its shape when cooked and cooled. The PGI status also means that Cornish pasties must be prepared in Cornwall. They do not have to be baked in Cornwall, nor do

They are, however, commercially available in the British supermarket chain Morrisons (under the name 'Tin Miner Pasty'). Other traditional fillings have included a wide variety of locally available meats including pork, bacon, egg, rabbit, chicken, mackerel and sweet fillings such as dates, apples, jam and sweetened rice - leading to

There is a mention in Havelok the Dane , another romance written at the end of the thirteenth century; in the 14th century Robin Hood tales; and in two plays by William Shakespeare . In the tin mines of Devon and Cornwall, pasties were associated with " knockers ", spirits said to create a knocking sound that was either supposed to indicate the location of rich veins of ore, or to warn of an impending tunnel collapse. To encourage

There is a humorous belief that the pastry on a good pasty should be strong enough to withstand a drop down a mine shaft, and indeed the barley flour that was usually used does make hard dense pastry. Although the officially protected Cornish pasty has a specific ingredients list, old Cornish cookery books show that pasties were generally made from whatever food

Another theory suggests that pasties were marked at one end with an initial and then eaten from the other end so that if not finished in one sitting, they could easily be reclaimed by their owners. The pasty is regarded as the national dish of Cornwall, and an early reference is from a New Zealand newspaper: In Cornwall, there

In 2014, China was the top producer of white arsenic with almost 70% world share, followed by Morocco, Russia, and Belgium, according to the British Geological Survey and the United States Geological Survey . Most arsenic refinement operations in the US and Europe have closed over environmental concerns. Arsenic is found in the smelter dust from copper, gold, and lead smelters, and
6565-591: The fields). The accidental use of arsenic in the adulteration of foodstuffs led to the Bradford sweet poisoning in 1858, which resulted in 21 deaths. From the late-18th century wallpaper production began to use dyes made from arsenic, which was thought to increase the pigment's brightness. One account of the illness and 1821 death of Napoleon I implicates arsenic poisoning involving wallpaper. Two arsenic pigments have been widely used since their discovery – Paris Green in 1814 and Scheele's Green in 1775. After

7070-417: The ingredients have to come from the county, though the CPA notes that there are strong links between pasty production and local suppliers of the ingredients. Packaging for pasties that conform to the requirements includes an authentication stamp, the use of which is policed by the CPA. Producers outside Cornwall objected to the PGI award, with one saying "[EU bureaucrats could] go to hell", and another that it
7171-515: The main kitchen. This section of the kitchen is in charge of making pastries, desserts, and other baked goods. Arsenic Arsenic is a chemical element with the symbol As and the atomic number 33. It is a metalloid and one of the pnictogens , and therefore shares many properties with its group 15 neighbors phosphorus and antimony . Arsenic is a notoriously toxic heavy metal . It occurs naturally in many minerals , usually in combination with sulfur and metals, but also as
7272-473: The meal. The pasty can be carried in the man's pocket. The term "Cornish pasty" has been in use since at least the early 1860s: The Cornish pasty, which so admirably comprises a dinner in itself—meat, potatoes, and other good things well cooked and made up into so portable a form—was a subject of much admiration, and reminded me of the old coaching days, when I secured a pasty at Bodmin in order to take it home to my cook, that it might be dissected and serve as
7373-550: The monks of St Albans Abbey "according to their custom, lived upon pasties of flesh-meat". In 1465, 5,500 venison pasties were served at the installation feast of George Neville , archbishop of York and chancellor of England. The earliest reference for a pasty in Devon or Cornwall can be found in Plymouth city records of 1509/10, which describe "Itm for the cooke is labor to make the pasties 10d". They were even eaten by royalty, as
7474-515: The oft-quoted joke that 'the Devil hisself was afeared to cross over into Cornwall for fear that ee'd end up in a pasty'. A pasty is known as a "tiddy oggy" when steak is replaced with an extra potato, "tiddy" meaning potato and "oggy" meaning pasty and was eaten when times were hard and expensive meat could not be afforded. Another traditional meatless recipe is 'herby pie' with parsley, freshly gathered wild green herbs and chives, ramsons or leeks and
7575-481: The other hand, overmixing results in long gluten strands that toughen the pastry. In other types of pastry such as Danish pastry and croissants , the characteristic flaky texture is achieved by repeatedly rolling out a dough similar to yeast bread dough, spreading it with butter, and folding it to produce many thin layers. Pastry chefs use a combination of culinary ability and creativity for baking, decoration, and flavoring with ingredients. Many baked goods require
7676-400: The pasties were ready for eating, the bal maidens at the mines would supposedly shout down the shaft "Oggy Oggy Oggy" and the miners would reply "Oi Oi Oi". As the 'national dish' of Cornwall, several oversized versions of the pasty have been created in the county. For example, a giant pasty is paraded from Polruan to Fowey through the streets during regatta week. Similarly, a giant pasty
7777-550: The pasty are unclear, though there are many references to them throughout historical documents and fiction. The pasty is now popular worldwide because of the spread of Cornish miners and sailors from across Cornwall, and variations can be found in Australia, Mexico, the United States, Ulster and elsewhere. Despite the modern pasty's strong association with Cornwall, its origins are unclear. The English word "pasty" derives from Medieval French (O.Fr. paste from V.Lat pasta ) for
7878-521: The pasty, as well as sweet pasties with ingredients such as apple and fig or chocolate and banana, which are common in some areas of Cornwall. A part-savoury, part-sweet pasty (similar to the Bedfordshire clanger ) was eaten by miners in the 19th century, in the copper mines on Parys Mountain , Anglesey . The technician who did the research and discovered the recipe claimed that the recipe was probably taken to Anglesey by Cornish miners travelling to
7979-422: The pasty-seller with his characteristic vendor's call who was always outside Plymouth's Devonport Naval Dockyard gates late at night when the sailors were returning, and his replacement by hot dog sellers after World War II. The word "oggy" in the internationally popular chant " Oggy Oggy Oggy, Oi Oi Oi " is thought to stem from Cornish dialect " hoggan ", deriving from "hogen" the Cornish word for pasty. When
8080-530: The plays of Aristophanes , written in the 5th century BC, there is mention of sweetmeats, including small pastries filled with fruit. Roman cuisine used flour, oil, and water to make pastries that were used to cover meats and fowls during baking in order to keep in the juices, but the pastry was not meant to be eaten. A pastry that was meant to be eaten was a richer pastry that was made into small pastries containing eggs or little birds and that were often served at banquets. Greeks and Romans both struggled in making
8181-408: The presence of mercury vapors. It is glassy and brittle. Black arsenic is also a poor electrical conductor. Arsenic sublimes upon heating at atmospheric pressure , converting directly to a gaseous form without an intervening liquid state at 887 K (614 °C). The triple point is at 3.63 MPa and 1,090 K (820 °C). Arsenic occurs in nature as one stable isotope , As, and
8282-938: The public uses bottled water . In Pakistan, more than 60 million people are exposed to arsenic polluted drinking water indicated by a 2017 report in Science . Podgorski's team investigated more than 1200 samples and more than 66% exceeded the WHO minimum contamination level. Since the 1980s, residents of the Ba Men region of Inner Mongolia, China have been chronically exposed to arsenic through drinking water from contaminated wells. A 2009 research study observed an elevated presence of skin lesions among residents with well water arsenic concentrations between 5 and 10 μg/L, suggesting that arsenic induced toxicity may occur at relatively low concentrations with chronic exposure. Overall, 20 of China's 34 provinces have high arsenic concentrations in
8383-444: The rate of decomposition. It oxidises readily in air to form arsenic trioxide and water, and analogous reactions take place with sulfur and selenium instead of oxygen . Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 (" white arsenic ") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic(V) acid is a weak acid and its salts, known as arsenates , are
8484-555: The rest of the world during the 19th century. As tin mining in Devon and Cornwall began to decline, miners took their expertise and traditions to new mining regions around the world. As a result, pasties can be found in many regions, including: When I view my Country o'er: Of goodly things the plenteous store: The Sea and Fish that swim therein And underground the Copper and Tin: Let all
8585-406: The same group (column) of the periodic table . The most common oxidation states for arsenic are: −3 in the arsenides , which are alloy-like intermetallic compounds, +3 in the arsenites , and +5 in the arsenates and most organoarsenic compounds. Arsenic also bonds readily to itself as seen in the square As 3− 4 ions in the mineral skutterudite . In the +3 oxidation state , arsenic
8686-443: The same structure as the more well-known phosphorus compounds, and in fluorine to give arsenic pentafluoride . Arsenic makes arsenic acid with concentrated nitric acid , arsenous acid with dilute nitric acid, and arsenic trioxide with concentrated sulfuric acid ; however, it does not react with water, alkalis, or non-oxidising acids. Arsenic reacts with metals to form arsenides , though these are not ionic compounds containing
8787-476: The stable As tend to decay by β decay , and those that are heavier tend to decay by β decay , with some exceptions. At least 10 nuclear isomers have been described, ranging in atomic mass from 66 to 84. The most stable of arsenic's isomers is As with a half-life of 111 seconds. Arsenic has a similar electronegativity and ionization energies to its lighter pnictogen congener phosphorus and therefore readily forms covalent molecules with most of
8888-575: The substance was frequently used for murder until the advent in the 1830s of the Marsh test , a sensitive chemical test for its presence. (Another less sensitive but more general test is the Reinsch test .) Owing to its use by the ruling class to murder one another and its potency and discreetness, arsenic has been called the "poison of kings" and the "king of poisons". Arsenic became known as "the inheritance powder" due to its use in killing family members in
8989-456: The toxicity of arsenic became widely known, these chemicals were used less often as pigments and more often as insecticides. In the 1860s, an arsenic byproduct of dye production, London Purple, was widely used. This was a solid mixture of arsenic trioxide, aniline, lime, and ferrous oxide, insoluble in water and very toxic by inhalation or ingestion But it was later replaced with Paris Green , another arsenic-based dye. With better understanding of
9090-451: The toxicology mechanism, two other compounds were used starting in the 1890s. Arsenite of lime and arsenate of lead were used widely as insecticides until the discovery of DDT in 1942. In small doses, soluble arsenic compounds act as stimulants , and were once popular as medicine by people in the mid-18th to 19th centuries; this use was especially prevalent for sport animals such as race horses or work dogs and continued into
9191-609: The trioxide, are used in the production of pesticides , treated wood products, herbicides , and insecticides . These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. Arsenic has been known since ancient times to be poisonous to humans. However, a few species of bacteria are able to use arsenic compounds as respiratory metabolites . Trace quantities of arsenic have been proposed to be an essential dietary element in rats, hamsters, goats, and chickens. Research has not been conducted to determine whether small amounts of arsenic may play
9292-403: The wealthy, during the 17th and 18th centuries, the pasty became popular with working people in Cornwall and west Devon, where tin miners and others adopted it because of its unique shape, forming a complete meal that could be carried easily and eaten without cutlery. In a mine, the pasty's dense, folded pastry could stay warm for several hours, and if it did get cold, it could easily be warmed on
9393-479: The west, which are generally much sweeter. Different kinds of pastry doughs are made by utilizing the natural characteristics of wheat flour and certain fats. When wheat flour is mixed with water and kneaded into plain dough, it develops strands of gluten, which are what make bread tough and elastic. In a typical pastry, however, this toughness is unwanted, so fat or oil is added to slow down the development of gluten. Pastry flour can also be used, since it typically has
9494-531: Was "protectionism for some big pasty companies to churn out a pastiche of the real iconic product". Major UK supermarkets Asda and Morrisons both stated they would be affected by the change, as did nationwide bakery chain Greggs , though Greggs was one of seven companies allowed to continue to use the name "Cornish pasty" during a three-year transitional period. Members of the CPA made about 87 million pasties in 2008, amounting to sales of £60 million (about 6% of
9595-489: Was also used in various agricultural insecticides and poisons. For example, lead hydrogen arsenate was a common insecticide on fruit trees , but contact with the compound sometimes resulted in brain damage among those working the sprayers. In the second half of the 20th century, monosodium methyl arsenate (MSMA) and disodium methyl arsenate (DSMA) – less toxic organic forms of arsenic – replaced lead arsenate in agriculture. These organic arsenicals were in turn phased out in
9696-407: Was available. Indeed, the earliest recorded pasty recipes include venison, not beef. "Pasty" has always been a generic name for the shape and can contain a variety of fillings, including stilton , vegetarian and even chicken tikka . Pork and apple pasties are readily available in shops throughout Cornwall and Devon, with the ingredients including an apple flavoured sauce, mixed together throughout
9797-451: Was found that addition of sulfur, phosphorus, and iron oxides to high-arsenite soils greatly reduces arsenic phytotoxicity. Arsenic is used as a feed additive in poultry and swine production , in particular it was used in the U.S. until 2015 to increase weight gain, improve feed efficiency , and prevent disease. An example is roxarsone , which had been used as a broiler starter by about 70% of U.S. broiler growers. In 2011, Alpharma,
9898-495: Was indicated for syphilis , but has been superseded by modern antibiotics . However, arsenicals such as melarsoprol are still used for the treatment of trypanosomiasis , since although these drugs have the disadvantage of severe toxicity, the disease is almost uniformly fatal if untreated. In 2000 the US Food and Drug Administration approved arsenic trioxide for the treatment of patients with acute promyelocytic leukemia that
9999-468: Was not until about the mid-16th century that actual pastry recipes began appearing. These recipes were adopted and adapted over time in various European countries, resulting in the myriad pastry traditions known to the region, from Portuguese " pastéis de nata " in the west to Russian " pirozhki " in the east. The use of chocolate in pastry-making in the west, so commonplace today, arose only after Spanish and Portuguese traders brought chocolate to Europe from
10100-583: Was the first organometallic compound known (even though arsenic is not a true metal) and was named from the Greek κακωδία "stink" for its offensive, garlic-like odor; it is very toxic. Arsenic is the 53rd most abundant element in the Earth's crust , comprising about 1.5 parts per million (0.00015%). Typical background concentrations of arsenic do not exceed 3 ng/m in the atmosphere; 100 mg/kg in soil; 400 μg/kg in vegetation; 10 μg/L in freshwater and 1.5 μg/L in seawater. Arsenic
10201-1020: Was widely criticised and subsequently refuted by independent researcher groups. Arsenic may be an essential trace mineral in birds, involved in the synthesis of methionine metabolites, with feeding recommendations being between 0.012 and 0.050 mg/kg. Some evidence indicates that arsenic is an essential trace mineral in mammals. However, the biological function is not known. Arsenic has been linked to epigenetic changes , heritable changes in gene expression that occur without changes in DNA sequence . These include DNA methylation, histone modification, and RNA interference. Toxic levels of arsenic cause significant DNA hypermethylation of tumor suppressor genes p16 and p53 , thus increasing risk of carcinogenesis . These epigenetic events have been studied in vitro using human kidney cells and in vivo using rat liver cells and peripheral blood leukocytes in humans.
