Bake the Ham:

1. Preheat oven to 275 F. Add 1/2 cup of water to the bottom of a roasting pan and place the rack on top.
2. Place ham flat side down on top of the rack. Score the ham with a knife to make shallow cuts, about 1/4-inch deep. This helps the ham soak in the sweet glaze. Cover the pan with foil to keep the ham from getting overcooked and dry.
3. Bake the ham covered for 2 hours until the internal temperature at the thickest part registers at 135F on a meat thermometer.

Add Glaze:

1. Increase the oven temperature to 425 F.
2. In a small bowl, combine brown sugar, honey, mustard, apple cider, cumin powder and cinnamon. Whisk until smooth, about 1 minute.
3. Remove the pan from the oven and generously brush half of the glaze over the ham to coat. Return the pan to the oven and bake uncovered for 15 minutes. Then repeat, applying the remaining glaze and baking for another 15 minutes until the ham caramelizes and turns brown.
4. Transfer to a serving platter and pour pan drippings on top. Slice and serve with cranberry sauce.
