Rub both sides of beef steaks with cut sides of garlic clove. Place steaks on rack in broiler pan so surface of beef is 2 to 3 inches from heat. Place well-trimmed steaks on grid over medium, ash-covered coals. Grill, uncovered, 13 to 15 minutes for medium rare to medium doneness, turning occasionally. One minute before steaks are done, top evenly with topping.
