Baking at 325 degrees should be the highest temperature or it will dry out. Low and slow will guarantee a wonderful result.
PREHEAT oven to 325 degrees.
Place the ham in a shallow roasting pan and baste with the cola. Using toothpicks, stick the pineapple rings over the top and sides of the ham. Sprinkle the brown sugar over the pineapple.
Place the cherries on top (in the middle of the pineapple rings). Stick a few cloves in the pineapple rings - securing all with toothpicks.
Cover with foil and bake 15 to 18 minutes per pound, or until the internal temperature reaches 140 degrees. Baste with cola every 30 minutes during cooking time.
