Things You'll Need
Spiral-sliced hams, which are smoked for a rich flavor, are fully cooked. The hams make convenient and tasty holiday dinner options. Because the hams are already cooked, you need only to reheat them for several hours in an oven before eating them. Spiral hams are sliced by a blade that makes one continuous cut all around the meat. Since the cuts are already made, it's simple to serve equal-sized individual portions. Top the ham with a handmade glaze to create a customized flavor.
Preheat an oven to 275 degrees Fahrenheit. Unwrap the spiral ham and place it in a roasting pan. Pour 3/4 cup of water around the ham.
Place a sheet of foil over the top of the pan tightly to prevent the ham from drying out in the oven.
Heat a quarter of a ham for one-and-a-half hours, a half ham for two hours and a whole ham for three hours, or until the ham is heated all the way through.
Take the ham out of the oven and spread a glaze over the top, using a pastry brush; allow the glaze to drip down onto the cut slices. Put the glazed ham back into the oven and heat it for an additional 10 to 20 minutes, or until the glaze is bubbly.
