The term London broil can confuse, because technically it is a method of grilling and slicing the meat rather than a specific cut of beef. However, supermarket cuts labeled London broil are most often cut from the flank. Both flank and top round offer good flavor, but they differ in texture.
You might find London Broil in anything from a 1-inch cut to a 4-inch roast. Marinate for 2 to 3 hours per inch and grill to no more than medium. On the thick roasts, you will want to grill it directly for about 2 to 4 minutes per side then indirectly for up to 30 minutes. The internal temperature should not pass 135 degrees F/55 degrees C.
