Meat comes from the muscle and other edible parts of animals and birds. Beef is obtained from domestic cattle, which can be steers, bulls, heifers, or cows. The quality of meat is affected by factors like the amount of connective tissue and fat. After slaughter, how the meat is treated also impacts its eating quality. The document then describes various cuts of beef, including topside, rump, sirloin, brisket, shin, and flank, and suggests cooking methods for each cut.
