Most common ham that is available in grocery stores is called city ham. It’s fully cooked, comes with or without bone, and most are spiral cut. This ham can be bought as a whole or a half. City ham is a breeze to prepare because it’s already cooked. The goal is to get flavor infused into it with glaze and re-heat it through to the right temperature. Boneless or bone-in will work but bone-in tends to have more flavor. Getting a spiral cut ham will make it easier on you.
