Preheat oven to 325 degrees. Wash excess fat off ham and dry completely. Score top of ham deeply and place in roasting pan. Pour vinegar over entire ham and place in oven.
Bake ham for 3 hours, pouring vinegar over ham at 30 minute intervals until the entire bottle is used up. Do not baste ham with drippings in bottom of pan. (The vinegar mellows the taste of the ham.)
While ham is baking, in a saucepan, combine chili sauce, brown sugar, mustard, honey , maple sy rup, pineapple and cloves and cook over medium heat until boiling. Remove from heat and spoon 1/2 of mixture over ham. Return ham to oven and bake 30 minutes; remove from oven and spoon remaining sauce over ham.
Bake another 30 minutes, then remove from oven, cover, and let stand 15 minutes until juices set. Slice and serve immediately. Makes lots. Enjoy!
