1. Prepare the oven to 250F, and unpack the spiral ham, setting the glaze packet aside. Put the ham on a roasting container and cover with the lid, or set a few layers of foil in the dish and place the ham on it.
2. Prepare the glaze packet as instructed and brush half of it over the spiral ham. Then, wrap it in foil, set the pan in the oven, and cook for 12 to 15 minutes per pound.
3. At the last quarter of the calculated cooking time, remove the roasting dish, unwrap the ham, and brush with the rest of the glaze. Then, increase the oven to 350F and cook the ham uncovered, or until the internal temperature hits 130F
4. Take the ham down, tent it in foil, and rest for 10 minutes so the final 140F temperature is reached.
