Smithfield spiral hams are thoroughly cooked and should be gently heated at 275 degrees. Remove the ham from its packaging, reserving the liquid. Place the ham cut-side down on foil in a large roasting pan. Pour the reserved liquid over the ham and completely wrap it in foil.
The ham should be warmed in the oven at 275 degrees for 10 to 12 minutes per pound.
Spiral sliced ham may be kept in the refrigerator for seven to 10 days. The ham can be stored in the freezer for up to three months to maintain maximum flavor. Smithfield offers spiral sliced hams in a variety of flavors that include honey cure, brown sugar cure and honey glaze.
