Place precooked ham in roasting pan. Score ham with knife about 1/4 to 1/2 inches deep to form squares or diamond shapes. Push cloves into each square. Arrange sliced pineapples and maraschino cherries on top of ham. Spoon Creole Mustard Glaze carefully over ham to cover thoroughly. Bake at 250° F for 2 hours. During baking continue to glaze ham occasionally.
Serve hot or cold with additional glaze.
