Also known as New York strip steak and shell steak, this cut of meat comes from the most tender section of beef, the short loin. It's the boneless top loin muscle and is equivalent to a porterhouse steak minus tenderloin and bone. Depending on the region, it's also marketed as Delmonico steak, Kansas City (strip) steak, sirloin club steak and strip steak. This tender cut may be broiled, grilled or sautéed.
