Pour ⅓ cup water into the bottom of the roasting pan and cover the ham with foil.
Bake in the oven for 1 hour and 25 minutes.
In a small saucepan over medium heat, mix together the remaining ingredients. Cook for 3-5 minutes until the mixture becomes bubbly and begins to thicken. Remove from heat and set aside.
Once the ham has baked for 1 hour and 25 minutes, remove from the oven and pour or brush the cranberry sauce onto the ham.
Return the glazed ham to the oven, uncovered, and cook for another 25 minutes.
Slice and serve.
