When it comes to preparing cooked ham for Christmas, there are several methods to consider. For a classic approach, try glazing the ham with a sweet and savory mixture of brown sugar, maple syrup, and dijon mustard. Alternatively, you can prepare a savory sauce using ingredients like orange juice, honey, and soy sauce. Or, if you prefer a more traditional approach, consider cooking the ham in a slow cooker with a variety of spices and herbs. Whichever method you choose, be sure to let the ham rest and slice thinly before serving.
