Beef

is the culinary name for meat from cattle (Bos taurus). In prehistoric times, humans hunted aurochs and later domesticated them. Since that time, numerous breeds of cattle have been bred specifically for the quality or quantity of their meat. Today, beef is the third most widely consumed meat in the world, after pork and poultry.

Beef can be prepared in various ways; cuts are often used for steak, which can be cooked to varying degrees of doneness, while trimmings are often ground or minced, as found in most hamburgers. Beef contains protein, iron, and vitamin B12. Along with other kinds of red meat, high consumption is associated with an increased risk of colorectal cancer and coronary heart disease, especially when processed. Beef has a high environmental impact, being a primary driver of deforestation with the highest greenhouse gas emissions of any agricultural product.

Etymology
The word beef is from the Latin bōs, in contrast to cow which is from Middle English cou (both words have the same Indo-European root ). After the Norman Conquest, the French-speaking nobles who ruled England naturally used French words to refer to the meats they were served. Thus, various Anglo-Saxon words were used for the animal (such as nēat, or cu for adult females) by the peasants, but the meat was called boef (ox) (Modern French bœuf) by the French nobles — who did not often deal with the live animal — when it was served to them. This is one example of the common English dichotomy between the words for animals (with largely Germanic origins) and their meat (with Romanic origins) that is also found in such English word-pairs as pig/pork, deer/venison, sheep/mutton and chicken/poultry (also the less common goat/chevon). Beef is cognate with bovine through the Late Latin bovīnus. The rarely used plural form of beef is beeves.

History
People have eaten the flesh of bovines since prehistoric times; some of the earliest known cave paintings, such as those of Lascaux, show aurochs in hunting scenes. People domesticated cattle to provide ready access to beef, milk, and leather. Cattle have been domesticated at least twice over the course of evolutionary history. The first domestication event occurred around 10,500 years ago with the evolution of Bos taurus. The second was more recent, around 7,000 years ago, with the evolution of Bos indicus in the Indus Valley. There is a possible third domestication event 8,500 years ago, with a potential third species Bos africanus arising in Africa. Most cattle originated in the Old World, with the exception of bison hybrids, which originated in the Americas. Examples include the Wagyū from Japan, Ankole-Watusi from Egypt, and longhorn Zebu from the Indian subcontinent.

Production
Beef cattle are raised and fed using a variety of methods, including feedlots, free range, ranching, backgrounding and intensive animal farming. Concentrated Animal Feeding Operations (CAFOs), commonly referred to as factory farms, are commonly used to meet the demand of beef production. CAFOs supply 70.4% of cows in the US market and 99% of all meat in the United States supply. Cattle CAFOs can also be a source of E. coli contamination in the food supply due to the prevalence of manure in CAFOs. These E. coli contaminations include one strain, E. coli O157:H7, which can be toxic to humans, because cattle typically hold this strain in their digestive system. Another consequence of unsanitary conditions created by high-density confinement systems is increased use of antibiotics in order to prevent illness. An analysis of FDA sales data by the Natural Resources Defense Council found 42% of medically important antibiotic use in the U.S. was on cattle, posing concerns about the development of antibiotic resistant bacteria.

Cuts
Most beef can be used as is by merely cutting into certain parts, such as roasts, short ribs or steak (filet mignon, sirloin steak, rump steak, rib steak, rib eye steak, hanger steak, etc.), while other cuts are processed (corned beef or beef jerky). Trimmings, on the other hand, which are usually mixed with meat from older, leaner (therefore tougher) cattle, are ground, minced or used in sausages. The blood is used in some varieties called blood sausage. Other parts that are eaten include other muscles and offal, such as the oxtail, liver, tongue, tripe from the reticulum or rumen, glands (particularly the pancreas and thymus, referred to as sweetbread), the heart, the brain (although forbidden where there is a danger of bovine spongiform encephalopathy, BSE, commonly referred to as mad cow disease), the kidneys, and the tender testicles of the bull (known in the United States as calf fries, prairie oysters, or Rocky Mountain oysters). Some intestines are cooked and eaten as is, but are more often cleaned and used as natural sausage casings. The bones are used for making beef stock. Meat from younger cows (calves) is called veal. Beef from steers and heifers is similar.

Beef is first divided into primal cuts, large pieces of the animal initially separated by butchering. These are basic sections from which steaks and other subdivisions are cut. The term "primal cut" is quite different from "prime cut", used to characterize cuts considered to be of higher quality. Since the animal's legs and neck muscles do the most work, they are the toughest; the meat becomes more tender as distance from hoof and horn increases. Different countries and cuisines have different cuts and names, and sometimes use the same name for a different cut; for example, the cut described as "brisket" in the United States is from a significantly different part of the carcass than British brisket.

Aging and tenderization
To improve tenderness of beef, it is often aged (i.e., stored refrigerated) to allow endogenous proteolytic enzymes to weaken structural and myofibrillar proteins. Wet aging is accomplished using vacuum packaging to reduce spoilage and yield loss. Dry aging involves hanging primals (usually ribs or loins) in humidity-controlled coolers. Outer surfaces dry out and can support growth of molds (and spoilage bacteria, if too humid), resulting in trim and evaporative losses.

Evaporation concentrates the remaining proteins and increases flavor intensity; the molds can contribute a nut-like flavor. After two to three days there are significant effects. The majority of the tenderizing effect occurs in the first 10 days. Boxed beef, stored and distributed in vacuum packaging, is, in effect, wet aged during distribution. Premium steakhouses dry age for 21 to 28 days or wet age up to 45 days for maximum effect on flavor and tenderness.

Meat from less tender cuts or older cattle can be mechanically tenderized by forcing small, sharp blades through the cuts to disrupt the proteins. Also, solutions of exogenous proteolytic enzymes (papain, bromelin or ficin) can be injected to augment the endogenous enzymes. Similarly, solutions of salt and sodium phosphates can be injected to soften and swell the myofibrillar proteins. This improves juiciness and tenderness. Salt can improve the flavor, but phosphate can contribute a soapy flavor.

Cooking methods
These methods are applicable to all types of meat and some other foodstuffs.

Internal temperature


Beef can be cooked to various degrees, from very rare to well done. The degree of cooking corresponds to the temperature in the approximate center of the meat, which can be measured with a meat thermometer. Beef can be cooked using the sous-vide method, which cooks the entire steak to the same temperature, but when cooked using a method such as broiling or roasting it is typically cooked such that it has a "bulls eye" of doneness, with the least done (coolest) at the center and the most done (warmest) at the outside.

Frying
Meat can be cooked in boiling oil, typically by shallow frying, although deep frying may be used, often for meat enrobed with breadcrumbs as in milanesas or finger steaks. Larger pieces such as steaks may be cooked this way, or meat may be cut smaller as in stir frying, typically an Asian way of cooking: cooking oil with flavorings such as garlic, ginger and onions is put in a very hot wok. Then small pieces of meat are added, followed by ingredients which cook more quickly, such as mixed vegetables. The dish is ready when the ingredients are 'just cooked'.

Moist heat
Moist heat cooking methods include braising, pot roasting, stewing and sous-vide. These techniques are often used for cuts of beef that are tougher, as these longer, lower-temperature cooking methods have time to dissolve connecting tissue which otherwise makes meat remain tough after cooking.
 * Stewing or simmering
 * simmering meat, whole or cut into bite-size pieces, in a water-based liquid with flavorings. This technique may be used as part of pressure cooking.


 * Braising
 * cooking meats, in a covered container, with small amounts of liquids (usually seasoned or flavored). Unlike stewing, braised meat is not fully immersed in liquid, and usually is browned before the oven step.


 * Sous-vide
 * Sous-vide, French for "under vacuum", is a method of cooking food sealed in airtight plastic bags in a water bath for a long time—72 hours is not unknown—at an accurately determined temperature much lower than normally used for other types of cooking. The intention is to maintain the integrity of ingredients and achieve very precise control of cooking. Although water is used in the method, only moisture in or added to the food bags is in contact with the food.

Meat has usually been cooked in water which is just simmering, such as in stewing; higher temperatures make meat tougher by causing the proteins to contract. Since thermostatic temperature control became available, cooking at temperatures well below boiling, 52 C (sous-vide) to 90 C (slow cooking), for prolonged periods has become possible; this is just hot enough to convert the tough collagen in connective tissue into gelatin through hydrolysis, with minimal toughening.

With the adequate combination of temperature and cooking time, pathogens, such as bacteria will be killed, and pasteurization can be achieved. Because browning (Maillard reactions) can only occur at higher temperatures (above the boiling point of water), these moist techniques do not develop the flavors associated with browning. Meat will often undergo searing in a very hot pan, grilling or browning with a torch before moist cooking (though sometimes after).

Thermostatically controlled methods, such as sous-vide, can also prevent overcooking by bringing the meat to the exact degree of doneness desired, and holding it at that temperature indefinitely. The combination of precise temperature control and long cooking duration makes it possible to be assured that pasteurization has been achieved, both on the surface and the interior of even very thick cuts of meat, which can not be assured with most other cooking techniques. (Although extremely long-duration cooking can break down the texture of the meat to an undesirable degree.)

Beef can be cooked quickly at the table through several techniques. In hot pot cooking, such as shabu-shabu, very thinly sliced meat is cooked by the diners at the table by immersing it in a heated pot of water or stock with vegetables. In fondue bourguignonne, diners dip small pieces of beef into a pot of hot oil at the table. Both techniques typically feature accompanying flavorful sauces to complement the meat.

Raw beef


Steak tartare is a French dish made from finely chopped or ground (minced) raw meat (often beef). More accurately, it is scraped so as not to let even the slightest of the sinew fat get into the scraped meat. It is often served with onions, capers, seasonings such as fresh ground pepper and Worcestershire sauce, and sometimes raw egg yolk.

The Belgian or Dutch dish filet américain is also made of finely chopped ground beef, though it is seasoned differently, and either eaten as a main dish or can be used as a dressing for a sandwich. Kibbeh nayyeh is a similar Lebanese and Syrian dish. And in Ethiopia, a ground raw meat dish called tire siga or kitfo is eaten (upon availability).

Carpaccio of beef is a thin slice of raw beef dressed with olive oil, lemon juice and seasoning. Often, the beef is partially frozen before slicing to allow very thin slices to be cut.

Yukhoe is a variety of hoe, raw dishes in Korean cuisine which is usually made from raw ground beef seasoned with various spices or sauces. The beef part used for yukhoe is tender rump steak. For the seasoning, soy sauce, sugar, salt, sesame oil, green onion, and ground garlic, sesame seed, black pepper and juice of bae (Korean pear) are used. The beef is mostly topped with the yolk of a raw egg.

Cured, smoked, and dried beef
Bresaola is an air-dried, salted beef that has been aged about two to three months until it becomes hard and a dark red, almost purple, colour. It is lean, has a sweet, musty smell and is tender. It originated in Valtellina, a valley in the Alps of northern Italy's Lombardy region. Bündnerfleisch is a similar product from neighbouring Switzerland. Chipped beef is an American industrially produced air-dried beef product, described by one of its manufacturers as being "similar to bresaola, but not as tasty."

Beef jerky is dried, salted, smoked beef popular in the United States.

Biltong is a cured, salted, air dried beef popular in South Africa.

Pastrami is often made from beef; raw beef is salted, then partly dried and seasoned with various herbs and spices, and smoked.

Corned beef is a cut of beef cured or pickled in a seasoned brine. The corn in corned beef refers to the grains of coarse salts (known as corns) used to cure it. The term corned beef can denote different styles of brine-cured beef, depending on the region. Some, like American-style corned beef, are highly seasoned and often considered delicatessen fare.

Spiced beef is a cured and salted joint of round, topside, or silverside, traditionally served at Christmas in Ireland. It is a form of salt beef, cured with spices and saltpetre, intended to be boiled or broiled in Guinness or a similar stout, and then optionally roasted for a period after. There are various other recipes for pickled beef. Sauerbraten is a German variant.
