Trim any fat from London broil. Place London broil in a plastic bag that’s set in a bowl, or place in a glass or plastic dish. For the marinade, in a small bowl, combine remaining ingredients. Add marinade; close bag securely or cover dish with plastic wrap. Marinate in the refrigerator for eight to 24 hours, turning occasionally. Prepare medium charcoal fire or preheat gas grill to medium. Remove from marinade. Discard marinade.

Grill, on a lightly greased rack, 20 to 25 minutes for medium doneness or as desired, turning meat over halfway through grilling time. Let stand 10 minutes before slicing into thin slices. Serves eight.
