The upper part of the cow's tail offers morsels of meat and is a valued source of collagen, which the bones release when they are simmered slowly in liquid. Use oxtail for soups and stews, or a braise. In addition, the balance between bone and meat makes oxtail a great addition to beef stocks and broths. A single oxtail usually weighs 2 pounds and yields about 1 cup of lean meat. Our oxtail comes in 2-pound packages.
