Ah, you wish to know how to bake a Christmas ham? Well, my dear friend, baking a ham is a simple but delicious holiday tradition that can add a festive touch to your meal. Here's what you'll need: a ham (bone-in or boneless), brown sugar, cloves, and your choice of spices such as mustard, honey, or pineapple.
