Preheat oven to 300 degrees.
Place the ham in a large roasting pan. Score the ham on all sides (use a knife to cut small diamond shapes on the ham)
Use toothpicks to affix pineapple slices and jalapeno slices to the ham. (note the picture in the post)
Bake the ham, covered, for 45 minutes. About halfway through, use a spoon to pour a bit of the juice in the pan back over the ham, return to cook.
Remove the cover and brush the ham, pineapple, and jalapeno with the glaze.
Bake for an additional 15 minutes or until golden brown and at an internal temp of 140degrees.
Let rest for 15 minutes before slicing.
