how to cut a london broil against the grain
Identify the grain of the London broil. It is similar to wood grain and resembles small lines running throughout the steak. Start cutting the London broil into 1/8-inch strips against the grain at a 45-degree angle. This is a slight angle, which will create diagonal cuts in the steak. Continue cutting until only steak strips remain. Serve the London broil with a prepared sauce to help keep the meat moist and juicy.
