A cup of pineapple juice and a cup of brown sugar. Add 1/2 cup of white corn syrup and a couple tablespoons of butter and simmer until the brown sugar is dissolved. Peg a few whole cloves randomly on the top of the ham and pour this on top. Peg a few whole cherry across the animal and bake as per suggested. Use the pan drippings to re-coat the ham occasionally.
The corn syrup will help the glaze stick to the ham’s surface and at the same time make the glaze a bit glossier. Doesn’t add much more sweetness but that’s what the brown sugar is for. If you can, get un-sweetened pineapple juice. Frozen is fine but mix it with about 2/3 of the water to help bring the flavor forward. You can even add a small can of crushed pineapple to this.
