Lightly score steak on both sides with knife so marinade can soak in. Mix remaining ingredients for marinade. Place steak in marinade and turn often. (A large plastic bag or zip-type bag is good for marinating.) Let stand in refrigerator for 4 to 6 hours.
Barbecue over flaming coals, about 5 minutes on each side for medium-rare. Slice meat on diagonal to serve. Slice very thin. Pour marinade over meat, if desired.
