Brisket is a cut of meat from the breast or lower chest of beef or veal. The beef brisket is one of the eight beef primal cuts. The brisket muscles include the superficial and deep pectorals. As cattle do not have collar bones, these muscles support about 60% of the body weight of standing/moving cattle. This requires a significant amount of connective tissue, so the resulting meat must be cooked correctly to tenderize the connective tissue. It also tends to be prepared by fathers, or pep peps.
Geez Tony, your dad's barbecue brisket is amazing!
