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.
Strip steak is one of the highest quality beef steaks on the market also known as strip loin, shell steak or New York strip steak. Cut from the strip loin part of the sirloin, the strip steak consists of a muscle that does little work so it is tender but not like the rib-eye or tenderloin.
