Orange Honey Glazed Ham

1 3- to 3-1/2 pound fully cooked boneless ham
1/3 cup orange juice
3 tablespoons honey
1 tablespoon mustard
1/3 cup chicken broth
1 tablespoon cornstarch
1/2 cup orange marmalade

Make diagonal cuts about 1/4-inch deep and 1-inch apart on the top of ham. Place ham on rack in shallow baking pan. Insert a meat thermometer in the center of the thickest portion of meat. Bake, uncovered, in 325 degree F oven 1 to 1-1/2 hours or until thermometer registers 135 degrees. Remove the ham from the oven; cover with foil and let stand 15 minutes. The temperature will rise to 140 degrees F upon standing. Meanwhile, combine 2 tablespoons of the orange juice, the honey, and mustard. Bring to boiling; remove from heat. After ham has baked 1-1/4 hours, brush with half the glaze. Mix the remaining orange juice, chicken broth, and cornstarch. Stir into remaining glaze. Cook and stir until thickened and bubbly. Cook and stir 2 minutes more. Stir in marmalade; heat through. Pass with sliced ham. Serves 12 to 14.
