Remove ham from packaging and discard plastic disk that covers the bone. Place the ham in the large oven bag and tie closed. Cut four slits (about 2 inches each) in the top of the bag. Transfer the bagged ham to a roasting pan and let it sit at room temperature for about 1 1/2 hours.

Heat oven to 300 degrees and bake the ham for 1 1/2 to 2 1/2 hours (until the internal temperature of the ham is about 110 degrees). About an hour into baking, start making the glaze by combining the jelly, 1/2 cup brown sugar, maple syrup, mustard, cinnamon and nutmeg in a medium saucepan. Bring the mixture to a boil and reduce the heat to low, simmering, until the mixture is very thick and syrupy, about 45 minutes. Stir often.

Combine the remaining brown sugar and dry mustard in a small bowl. Remove ham from oven and increase the oven temperature to 400. Cut open oven bag. Using a pastry brush, paint the glaze onto the top and sides of the ham. Carefully press the sugar mixture onto the outside of the ham with your hands. Return the ham to the oven and bake until it is dark brown and caramelized, 14-16 minutes. Let the ham sit for 15 minutes before carving.
