Move oven rack to a position where the ham will bake centered in the oven. Preheat oven to 325° Fahrenheit.
Remove ham from package and cut the thick skin off if it is on the ham. Place flat side down in the roasting pan. Pour water into the bottom of the pan.
6-12 pound ham, ½ cup water
Place the pineapple slices with a cherry in the center of each slice all over the ham. Use toothpicks through the cherry to secure the fruit in place. Set the pineapple juice aside for glaze.Insert thermometer probe if you are using it.
Loosely cover the ham with foil, place in the oven and bake for about 15-20 minutes per pound.
About 1 hour before the cook time is up make the glaze. Combine the pineapple juice, brown sugar (light or dark), cherry juice and mustard in a small pot.Bring to a gentle simmer and cook stirring often for about 25-30 minutes, until it has thickened a bit. It should be a thickened but still pourable liquid. Set aside until putting on the ham.
pineapple juice from the canned slices, ¼ cup brown sugar, 3 Tablespoons cherry juice, 1 Tablespoon spicy mustard
Once the ham reaches about 130° Fahrenheit or about 15-20 minutes left of the cook time, remove from oven and spoon the glaze evenly over the ham and fruit.Bake uncovered for about 20 minutes, until the ham reaches 140° Fahrenheit. If you want a caramelized glaze, bake the last 20 minutes at 425°. If you prefer it to not caramelize, bake the last 20 minutes at 325°.
Remove from oven once it reaches 140° and allow it to rest at least 15 minutes before cutting.
Notes
Nutritional values and serving sizes are estimated. I do not recommend using a spiral ham, they dry out while cooking. Butt end is best for texture but shank is a good choice too. We use either one but often prefer the butt end.You can use Dijon mustard in place of spicy mustard.This recipe is for preparing a precooked ham. Most of the hams you buy from the store are precooked but check the package before preparing. If you have an uncooked ham, it needs to be cooked to at least 145 degrees Fahrenheit.
