Baked Ham with Brown Sugar Glaze

6 to 8 pounds fully cooked smoked bone-in ham
Whole cloves, if desired
1 cup packed brown sugar
1 tablespoon balsamic or cider vinegar
1/2 teaspoon ground mustard
Orange slices, if desired
Maraschino cherries, if desired

Heat oven to 325�F. Place ham, fat side up, on rack in shallow roasting pan. Insert meat thermometer so tip is in thickest part of ham and does not touch bone or rest in fat. Cover loosely and bake 1 1/4 to 2 1/4 hours or until thermometer reads 135 F (13 to 17 minutes per pound).

About 20 minutes before ham is done, remove from oven. Pour drippings from pan. Remove any skin from ham. Cut uniform diamond shapes on fat surface of ham. Insert clove into each diamond. Stir together brown sugar, vinegar and mustard; pat or brush on ham. Bake uncovered 20 minutes longer.
