Amish Sugar Glazed Ham Recipe

1 (5-7 lb)   Ham, fully cooked (bone in)
1 cup         Brown sugar, packed
2 tsp          Prepared mustard
1-2 tsp       Cider vinegar

Score ham about ½” deep with a sharp knife.  Place ham on a rack in 
a shallow baking pan.  Bake at 325 degrees for 2 to 2-1/2  hours ( 20 
minutes per lb).  Combine brown sugar, mustard and enough vinegar 
to make a thick paste.  During the last hour of baking, brush glaze on 
ham every 15 minutes.  Yield: 10-14 servings.
