1 half ham (5 - 6 lb.), fully cooked
2 qt. apple cider or juice
1 c. brown sugar
2 tsp. dry mustard
1 tsp. ground cinnamon
Cloves

RAISIN SAUCE:
2 c. cider, from ham
1/2 c. currants
1/4 tsp. cloves
1 tsp. cornstarch mixed with 1 tbsp. cider

Simmer cider, currants and cloves in small sauce pan about 
10 minutes. Stir in cornstarch mixture and simmer, stirring 
until sauce thickens slightly, about 3 to 5 minutes.

Soak ham overnight in cider in large pan in refrigerator, skin side down. Remove ham from pan and drain cider into medium sauce pan. Place ham on rack in roasting pan and bake at 350 degrees for about 2 hours (20 minutes per pound). Baste occasionally with cider. Remove ham from oven and strip off skin, if necessary. Score ham. Mix brown sugar, mustard and cinnamon and spread over ham. Stud ham with cloves. Return to oven and continue to bake 30 minutes at 350 degrees, basting occasionally with cider. Let set 20 minutes before carving. Serve with Raisin Sauce.
