Spiral hams are the tricksters of the holiday meal. They look intimidating because they can weigh 7 pounds and be bulky. But they are also incredibly easy to cook.
The trick is to take the doctor’s approach. First rule of spiral hams: Do no harm.
What you might not know about spiral ham is that you actually don’t need to cook them at all. They're completely cooked already, so you could literally just open the ham and serve it without touching it.
But that’s not very fun, right? Also, cold ham is good in sandwiches but not for your holiday guests.
So we can do better by cooking the ham, or more specifically, warming the ham. The danger: since the ham is already cooked, it's really easy to dry out.
