How to Cook a Smoked Ham?

A smoked ham is already cooked, so mainly you are just heating it up. Turn your oven to 325 degrees and put your ham in a pan. Put about 1/2 cup of water into the bottom of the pan and cover the ham with foil. About an hour in the oven should be enough to heat it through and through. If the ham is really big, it make take a little longer.
