Awesome Baked Ham

I love this recipe because it is so easy and it calls for hardly any ingredients, and I always have these ingredients in my pantry. This recipe came from a good friend's mother, who was always asked to bake the ham for get-togethers and family dinners. Now I get those requests.
Ingredients:

• 15 lbs whole bone-in ham (I prefer Cooks SuperTrim brand)
• 1 lb brown sugar
• 1/2 cup yellow mustard
• aluminum foil

Directions:

• In a medium size mixing bowl, mix yellow mustard and brown sugar until you have a thick"paste".
• Take all wrappers off of ham and trim away excess fat.
• Line baking pan (I spray with Pam in case some of the brown sugar mixture escapes, clean up is easier) with Aluminum foil.
• Place ham on foil and spread brown sugar/mustard paste on top.
• Fold and seal foil.
• Do not open again until ham is done.
• Bake at 350° for 4 hours.
• Let set for about 1 hr then carve.
• One of the best tasting hams you will ever have!
