Barbecued Round Steak Recipe

Combine oil and vinegar. Place steak in large bowl or baking pan. Pour oil and vinegar mixture over steak; marinate overnight in refrigerator, turning several times. Remove one hour before serving time; drain when ready to broil, saving marinade. Combine ketchup, Worcestershire sauce, Tabasco sauce, sugar, salt and pepper; add 3/4 cup marinade. Heat thoroughly. Place steak on greased grill over coals. Grill until done to taste, basting twice with the hot sauce. Allow 8 minutes each side for rare, 10 minutes each side for medium, 12-14 minutes each side for well done. Cut into serving pieces; serve with hot sauce. 6 servings.
