1 boneless fully cooked ham ( 5-6 pounds)
3/4 cups of water that will be used in parts
1 cup of packed brown sugar
4 1/2 teaspoons of soy sauce
4 1/2 teaspoons of ketchup
1 1 /2 teaspoons of ground mustard
1 1/2 cups of crushed undrained pineapple
2 tablespoons plus 1 teaspoon of cornstarch
Take heavy duty aluminum foil and line a shallow roasting pan. This will make clean up easy and fast. Place the ham on a rack in a shallow roasting pan. Bake at 325 degrees for 1 1/4 to 2 hours or until the meat thermometer reads 140 degrees and the ham is heated through.
In a saucepan, combine a 1/4 cup of water, brown sugar, soy sauce, ketchup, mustard and pineapple. Bring to a boil. Reduce the heat and cover and simmer for about 10 minutes.
Mix the cornstarch and remaining water until smooth. Stir this into the pineapple sauce. Bring this to a boil. Cook and stir for 2 minutes or until thickened. Serve with the ham.
