where is rump roast on a cow
Because bottom round rump roast comes from the well-exercised hindquarters of the cow, it contains a large amount of collagen and connective tissue that make the meat tough and chewy. A rump roast with the U.S. Department of Agricultureâs grade of Choice means that the beef has less marbling from fat than beef graded Prime, which also contributes to its toughness.
