When I bake a ham, I stick round pineapple slices all over the ham with toothpicks & cloves. (sometimes, I put maraschino cherries on it, too) Then I melt butter along with brown sugar & fruit juice (usually the pineapple juice from the pineapples but ANY fruit juice works) & sometimes, cinnamon & nutmeg, which I pour over the ham while it bakes & use to baste the throughout the baking time.
When the ham is nicely baked and browned, all of the juices from the basting mixes with the ham juices and I make a gravy from that. It's really good! I haven't made this in years, but whenever I used to make make it, it was a big hit.
OR you can make a redeye gravy, like Vrai posted.
