Cooking, cookery, or culinary arts is the art, science and craft of using heat to make food more palatable, digestible, nutritious, or safe. Cooking techniques and ingredients vary widely, from grilling food over an open fire to using electric stoves, to baking in various types of ovens, reflecting local conditions.
Ham is pork from a leg cut that has been preserved by wet or dry curing, with or without smoking. As a processed meat, the term "ham" includes both whole cuts of meat and ones that have been mechanically formed.
A potato chip or crisp is a thin slice of potato that has been deep fried, baked, or air fried until crunchy. They are commonly served as a snack, side dish, or appetizer. The basic chips are cooked and salted; additional varieties are manufactured using various flavorings and ingredients including herbs, spices, cheeses, other natural flavors, artificial flavors, and additives.
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH2=CHC(O)NH2. It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH2). It is produced industrially mainly as a precursor to polyacrylamides, which find many uses as water-soluble thickeners and flocculation agents.
Bacon is a type of salt-cured pork made from various cuts, typically the belly or less fatty parts of the back. It is eaten as a side dish, used as a central ingredient, or as a flavouring or accent.
Salami is a cured sausage consisting of fermented and air-dried meat, typically pork. Historically, salami was popular among Southern, Eastern, and Central European peasants because it can be stored at room temperature for up to 45 days once cut, supplementing a potentially meager or inconsistent supply of fresh meat. Countries and regions across Europe make their own traditional varieties of salami.
Instant coffee is a beverage derived from brewed coffee beans that enables people to quickly prepare hot coffee by adding hot water or milk to coffee solids in powdered or crystallized form and stirring. The product was first invented in Invercargill, the largest city in Murihiku, New Zealand, in 1890. Instant coffee solids refers to the dehydrated and packaged solids available at retail used to make instant coffee. Instant coffee solids are commercially prepared by either freeze-drying or spray drying, after which it can be rehydrated. Instant coffee in a concentrated liquid form, as a beverage, is also manufactured.
The Maillard reaction is a chemical reaction between amino acids and reducing sugars to create melanoidins, the compounds which give browned food its distinctive flavor. Seared steaks, fried dumplings, cookies and other kinds of biscuits, breads, toasted marshmallows, and many other foods undergo this reaction. It is named after French chemist Louis Camille Maillard, who first described it in 1912 while attempting to reproduce biological protein synthesis. The reaction is a form of non-enzymatic browning which typically proceeds rapidly from around 140 to 165 °C. Many recipes call for an oven temperature high enough to ensure that a Maillard reaction occurs. At higher temperatures, caramelization and subsequently pyrolysis become more pronounced.
Malay cuisine is the traditional food of the ethnic Malays of Southeast Asia, residing in modern-day Malaysia, Indonesia, Singapore, Brunei, Southern Thailand and the Philippines as well as Cocos Islands, Christmas Island, Sri Lanka and South Africa.
Raw foodism, also known as rawism or a raw food diet, is the dietary practice of eating only or mostly food that is uncooked and unprocessed. Depending on the philosophy, or type of lifestyle and results desired, raw food diets may include a selection of fruits, vegetables, nuts, seeds, eggs, fish, meat, and dairy products. The diet may also include simply processed foods, such as various types of sprouted seeds, cheese, and fermented foods such as yogurts, kefir, kombucha, or sauerkraut, but generally not foods that have been pasteurized, homogenized, or produced with the use of synthetic pesticides, fertilizers, solvents, and food additives.
Biryani is a mixed rice dish originating among the Muslims of South Asia. It is made with Indian spices, vegetables, rice, and usually some type of meat, or in some cases without any meat, and sometimes, in addition, eggs and potatoes.
Heston Marc Blumenthal is an English celebrity chef, TV personality and food writer. Blumenthal is regarded as a pioneer of multi-sensory cooking, food pairing and flavour encapsulation. He came to public attention with unusual recipes, such as bacon-and-egg ice cream and snail porridge. His recipes for triple-cooked chips and soft-centred Scotch eggs have been widely imitated. He has advocated a scientific approach to cooking, for which he has been awarded honorary degrees from Reading, Bristol and London universities and made an honorary Fellow of the Royal Society of Chemistry.
Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavors, and colors. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with microorganisms that convert lactose to lactic acid; an example of preventing a process would be stopping the browning on the surface of freshly cut apples using lemon juice or other acidulated water.
Toast is sliced bread that has been browned by radiant heat. The browning is the result of a Maillard reaction altering the flavor of the bread and making it firmer. The firm surface is easier to spread toppings on and the warmth can help butter reach its melting point. Toasting is a common method of making stale bread more palatable. Bread is toasted using a toaster or a toaster oven. Toast may contain acrylamide caused by the browning process, which is suspected to be a carcinogen. However, claims that acrylamide in burnt toast causes cancer have not been proven.
Shallow frying is a hot oil-based cooking technique. It is typically used to prepare portion-sized cuts of meat, fish, potatoes and patties such as fritters. Shallow frying can also be used to cook vegetables.
Glycidamide is an organic compound with the formula H2NC(O)C2H3O. It is a colorless, oil. Structurally, it contains adjacent amides and epoxide functional groups. It is a bioactive, potentially toxic or even carcinogenic metabolite of acrylonitrile and acrylamide. It is a chiral molecule.
Utilis Coquinario is an English cookery book written in Middle English at the turn of the fourteenth century. The title has been translated as "Useful for the Kitchen". The text is contained in the Hans Sloane collection of manuscripts in the British Library and is numbered Sloane MS 468.
Harry Erwin Nursten was a British food chemist, specialising in flavour chemistry at the Department of Nutrition and Food Sciences at the University of Reading.
A salt crust is a method of cooking by completely covering an ingredient such as fish, chicken or vegetables in salt before baking. The salt layer acts as insulation and helps cook the food in an even and gentle manner. After baking, the salt crust is cracked and discarded, revealing the moist and evenly cooked food.
David Julian McClements is a British food scientist who is a distinguished professor at the University of Massachusetts Amherst Department of Food Science. He is an elected fellow of the Royal Society of Chemistry, American Chemical Society, and Institute of Food Technologists, as well as the editor of the Annual Review of Food Science and Technology.
