1/2 c. orange marmalade
1 tsp. Worcestershire sauce
6 (6-8 oz.) slices of fully cooked ham about 1" thick
1/4 c. prepared mustard
1/4 c. plus 2 tbsp. water

Combine all ingredients except ham slices and mix well. Place ham slices in large baking dish or pan. Pour mixture over, turning to coat; marinate in refrigerator about 1 hour. Remove ham from marinade, reserving marinade for basting. Place ham 4-5 inches from slow to medium coals or heat. Grill 30-45 minutes, turning frequently and basting with marinade. Makes 6 servings.
