MargarineMargarine ('ma:rdZ@ri:n, also 'ma:rg@-,,ma:rg@'ri:n,,ma:rdZ@-, ˈmɑːrdʒərɪn) is a spread used for flavoring, baking, and cooking. It is most often used as a substitute for butter. Although originally made from animal fats, most margarine consumed today is made from vegetable oil. The spread was originally named oleomargarine from Latin for oleum (olive oil) and Greek margarite ("pearl", indicating luster). The name was later shortened to margarine.
PorkPork is the culinary name for the meat of the pig (Sus domesticus). It is the most commonly consumed meat worldwide, with evidence of pig husbandry dating back to 5000 BCE. Pork is eaten both freshly cooked and preserved; curing extends the shelf life of pork products. Ham, gammon, bacon, and pork sausage are examples of preserved pork. Charcuterie is the branch of cooking devoted to prepared meat products, many from pork. Pork is the most popular meat in the Western world, particularly in Central Europe.
TallowTallow is a rendered form of beef or mutton fat, primarily made up of triglycerides. In industry, tallow is not strictly defined as beef or mutton fat. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point. Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. The adjacent diagram shows the chemical structure of a typical triglyceride molecule.
ShorteningShortening is any fat that is a solid at room temperature and used to make crumbly pastry and other food products. The idea of shortening dates back to at least the 18th century, well before the invention of modern, shelf-stable vegetable shortening. In the earlier centuries, lard was the primary ingredient used to shorten dough. The reason it is called shortening is that it makes the resulting food crumbly, or to behave as if it had short fibers. Solid fat prevents cross-linkage between gluten molecules.
British cuisineBritish cuisine is the specific set of cooking traditions and practices associated with Great Britain, and includes the individual cuisines of England, Scotland and Wales. According to food writer Colin Spencer, historically, British cuisine meant "unfussy dishes made with quality local ingredients, matched with simple sauces to accentuate flavour, rather than disguise it". International recognition of British cuisine was historically limited to the full breakfast and the Christmas dinner.
Rendering (animal products)Rendering is a process that converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale. It can also be applied to non-animal products that are rendered down to pulp. The rendering process simultaneously dries the material and separates the fat from the bone and protein, yielding a fat commodity and a protein meal.
Iodine valueIn chemistry, the iodine value (IV; also iodine absorption value, iodine number or iodine index) is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine numbers are often used to determine the degree of unsaturation in fats, oils and waxes. In fatty acids, unsaturation occurs mainly as double bonds which are very reactive towards halogens, the iodine in this case. Thus, the higher the iodine value, the more unsaturations are present in the fat.
Deep fryingDeep frying (also referred to as deep fat frying) is a cooking method in which food is submerged in hot fat, traditionally lard but today most commonly oil, as opposed to the shallow oil used in conventional frying done in a frying pan. Normally, a deep fryer or chip pan is used for this; industrially, a pressure fryer or vacuum fryer may be used. Deep frying may also be performed using oil that is heated in a pot. Deep frying is classified as a hot-fat cooking method.
Fish and chipsFish and chips is a hot dish consisting of fried fish in batter, served with chips. The dish originated in England, where these two components had been introduced from separate immigrant cultures; it is not known who combined them. Often considered Britain's national dish, fish and chips is a common takeaway food in numerous other countries, particularly English-speaking and Commonwealth nations. Fish and chip shops first appeared in the UK in the 1860s and by 1910 there were over 25,000 across the UK.
Oleic acidOleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9, and a main product of Δ9-desaturase. It has the formula . The name derives from the Latin word oleum, which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates.
