This is cut from the boneless part of the flank and is secreted between an outside and inside layer of creamy fat. There are two ways for broiling it. One is to slice diagonally across the grain; the other is to broil it whole. In either case brush butter over it and proceed as in broiling other steaks. It is considered by butchers the finest steak, which they frequently reserve for themselves.
