Preheat Oven 325
Place ham, cut side down, in baking pan. Score the rind about 1/8 inch deep into 1 1/2 inch diamonds. Insert a clove into the center of each diamond. Arrange pineapple slices over the exposed area by inserting a cherry in the center of each one with a toothpick.
Mix the pineapple liquid with the brown sugar and 2 tablespoons of cherry liquid. Pour over the ham and bake according to your recipe (about 2 1/2 hours for an 8-pound ham; about 31/2 hours for a 16-pound ham). Baste ham and pineapple about every 30 minutes to coat pineapple and keep it moist.
Remove from oven and let rest for about 30 minutes before slicing. Remove toothpicks, pineapple, cherries and cloves. Pineapple and cherries go well served on the side.
