How to Make It
Preheat the oven to 375°. Place the ham on a rack set in a large roasting pan. Pour 1 cup of the apple juice over the ham, cover with foil and roast for 1 hour, basting with 1/2 cup of apple juice every 15 minutes. Continue roasting for 1 hour longer, basting twice with the pan juices.
In a small bowl, whisk the honey with the brown sugar, mustard, black pepper and cayenne, if using. Remove the foil from the ham and brush it all over with the glaze. Roast the ham for about 30 minutes longer, until the glaze is caramelized and an instant-read thermometer inserted in the thickest part of the meat registers 140°.
Transfer the ham to a platter and let rest for 10 minutes before slicing and serving.
