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. Serve warm sauce with ham.
This is my favourite ham recipe. It's easy to make and comes out well every time.
