Prime grade beef is the absolute highest quality beef available, graded by the USDA. This is a very rare, and thus very expensive, only averaging about 3% of all carcasses. The beef has very minor, but a good amount of fat running through the meat, resulting in an amazingly juicy and tender cooked piece of meat.
Beef round eye round roast is cut from eye round muscle removed from bottom round. It is naturally boneless, with an elongated shape and a slight fat covering. It is usually prepared by braising or roasting.
