Easter Ham

1 7 to 8 pound fully cooked smoked ham shank
1 cup maple syrup
2 Tablespoons cider vinegar
1 Tablespoon prepared mustard
whole cloves

Combine syrup, vinegar and mustard. Place ham, fat side up, on rack in shallow roasting pan. Pour about 1/2 cup mixture over ham and bake, uncovered, in a preheated 325 degree oven for 1-1/2 hours. Baste every 30 minutes with additional sauce. Remove ham from oven and score fat into diamond shapes. Insert a clove into each diamond. Bake ham an additional 30 minutes or until a meat thermometer inserted into the thickest part of meat registers 140 degrees. Let ham rest 15 minutes before carving. Makes 10 to 12 servings.
