Remove skin and excess fat from smoked ham; place ham in a lightly greased 13- x 9-inch pan.
Stir together maple syrup and next 3 ingredients.
Pour mixture over ham.
Bake at 350 on lower oven rack 2 hours and 30 minutes or until a meat thermometer inserted into thickest portion registers 140, basting every 20 minutes with glaze.
Let ham stand 10 minutes.
Remove from pan, reserving drippings. If desired, cool, cover, and chill ham.
Remove fat from drippings with a fat separator, and discard. Cover and chill drippings, if desired. Cook drippings, raisins, and apple slices in a saucepan over low heat 5 minutes.
