Beef
Beef is the culinary name for meat from cattle, particularly skeletal muscle. Humans
have been eating beef since prehistoric times. Beef is a source of high-quality
protein and nutrients. Most beef skeletal muscle meat 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,
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.
