Preheat oven to 325F.

Score ham lightly across the skin side.

Place cut side down in a square casserole dish or glass brownie pan and pour juice from the canned pineapple around it.

Pin pineapple rings and cherries to the ham using toothpicks.

Tent ham with foil (it doesn't matter if the toothpicks poke through).

Bake, covered, at 325F for 30 minutes.

Meanwhile, mix brown sugar, corn syrup, pineapple juice and cloves in a pyrex measurng cup and stir.

Microwave mixture for 30 seconds to 1 minute, stirring halfway through, until the sugar dissolves into a thick syrup; set aside.

Remove foil from ham and using a silicone basting brush, paint the syrup mixture around the top and sides of ham.

Return to oven, uncovered, and bake for another 30-60 minutes or until hot, basting occasionally with pan juices.

Slice ham before serving and serve with a garnish of pineapple and cherry.
