My best tips for a juicy ham are: - Reserve the liquids in the packaging and pour over the ham before any seasonings are added. - Once ready to heat, cover tightly with foil making sure the steam is not able to release.* - Heat in the CENTER of your oven. - Use lower temperatures in the 275-325 range to reheat. *you may remove foil and broil or bake the last few minutes to caramelize any seasonings!
