Australian Grass Fed Sirloin beef. Sirloin is cut from boned loin. It is tender, fine, close grained meat with exterior fat along one side. A line of gristle lies under the fat layer. Not quite as succulent as rib eye but an excellent grilling steak. Sirloin can be roasted at high or low temperatures, grilled or pan fried. In the U.S., this is a NY strip.
