To cook a Smithfield spiral cut ham, tightly seal the ham using a large piece of aluminum foil and bake at 325 degrees Fahrenheit for 12 minutes per pound. Heat the glaze packet that comes with the ham and brush the glaze over the ham.
Remove the Smithfield spiral cut ham from the oven one half-hour before baking time ends. Squeeze the glaze from the packet into a small saucepan, and mix in 2 tablespoons warm water. Cook glaze over high heat, stirring constantly, until glaze is warm. Brush the glaze over the entire surface of the ham, and return ham to the oven to finish baking.

Alternatively, its honey cured option has a natural baked-in sweetness, and customers can add more sweetness by brushing the outside with glaze.
