Need advice on a ham

I’m assuming the ham is already smoked? Or are you smoking a fresh ham?

What do you want to do with it, heat it up to serve? If so, you glaze it. Take the ham and cut the top like a checker board pattern. Make a glaze (google recipes). Pour the glaze on top of the ham and bake it, spooning the glaze/liquid back on top every 15-30 minutes.

You don’t season it. Search for a glaze online and go for it.

Recipe

Here’s a recipe I found with a quick search. Looks like it has all the info you need. Don’t overthink it, hams are easy.

I do one every year. Bone in, not spiral sliced. I place it on a rack over a pan of water. Smoker set at 275. I like maple wood. Stick a probe in the deepest part and when it hits 125 internal I start glazing it. There's a million simple recipes online for glazes. I pull it when the internal hits 140. Tent it and rest it for 20 minutes.

FYI. The ham is smoked and fully cooked, so the internal temperature doesn’t matter for safety reasons.
