London broil

London broil is a beef dish made by grilling marinated beef, then cutting it across the grain into thin strips. While the inclusion of "London" in the name may suggest British origins, "broil" is not a common term in UK English, and indeed the dish is American, not British. "London broil" originally referred to grilled flank steak, although modern butchers may label top round, coulotte, or other cuts as "London broil", and the term has come to refer more to a method of preparation and cookery than to a specific cut of meat. The preparation of London broil typically involves marinating the meat for several hours followed by high heat searing in an oven grill or outdoor grill. It is then served in thin slices, cut across the grain.
