In a small bowl, combine mustard, honey and brown sugar. If there's a bone in ham, remove it. Divide ham steak into 4 pieces; spread half of honey-mustard mixture on one side and stud each piece with a clove.
Turn broiler to high and place rack 2 inches from heat source. Put steaks on broiler pan and broil for about 4 minutes. Turn steaks over. Spread remaining mustard mixture over steaks, stud with remaining cloves and broil for about 4 minutes longer, until well-browned.
