Preheat your oven to 350°F and place your ham (fatty side up) in a large roasting pan or baking dish with 3/4 cup of water. Cover the ham with foil and roast for 1 hour.
Meanwhile, stick the rest of the ingredients into a blender and blend until smooth. Set the glaze aside.
After an hour, take off the foil and peel off the rind. With a sharp knife, cut crisis crosses across the fat cap (about 1/2″ deep). Generously brush the ham with glaze, making sure you get it into all the nooks and crannies! Bake for another 2 hours, brushing the meat with glaze again at the 1-hour mark and the 1.5-hour mark. The ham is ready when the fat starts to crisp and the glaze has caramelized. Let the ham rest for 5 – 10 minutes before carving.
Notes
