Bake for 1 ½ hours then turn oven to 425 degrees F and brush ham again with half of the remaining glaze.
Bake 15 additional minutes, then finally brush ham with remaining glaze you have. Place ham under broiler for 3-5 minutes to allow glaze to get sticky. The sugar should be super seeped in and delicious.
Rest ham for 10 minutes and then serve.
