There are numerous variations of brown sugar sauce for ham. One such recipe includes 1/2 cup of brown sugar, 1/3 cup of honey, 2 tablespoons of butter, 1 teaspoon of cornstarch and 1/4 teaspoon ground cloves.
Combine all the ingredients in a saucepan over low heat. Cook the sauce until it is melted and smooth, about three to five minutes. For a brown sugar sauce with a hint of tang, mix 1 cup of brown sugar, 1 tablespoon of cider vinegar or balsamic vinegar, and 1/2 teaspoon of ground nutmeg. For a tangy version, use 1/2 cup of brown sugar, 1/2 cup of maple syrup and 1/2 cup of honey Dijon mustard.
To develop deep caramelized color and flavor, score the top of the ham with cuts that are about 1/4 inch deep and 1 inch apart. Apply 1/3 of the brown sugar sauce to the ham before putting the ham in the oven. Baste the ham with the sauce every 30 minutes. Another option is to remove the ham approximately 20 minutes before it is done, baste it with all the brown sugar sauce and cook the ham uncovered for the remaining 20 minutes. If cooking a ham in a slow cooker, pour the brown sugar sauce over the ham before beginning the cooking process, then cover the ham and cook it.
