Preheat the oven to 325 degrees F. Score the top of the ham in a diamond pattern, making shallow cuts 1-inch apart. Place the ham in a small, parchment paper-lined baking pan. Bake, uncovered, for 30 minutes, and then brush with 1/2 the glaze. Bake for 15 minutes more, and then brush with the remaining glaze. Bake 15 minutes more, or until richly glazed and well heated through.
