How to Make It
Preheat oven to 325°. Place ham, cut side down, on a lightly greased (with cooking spray) rack in a heavy-duty aluminum foil-lined broiler pan; let stand at room temperature 30 minutes.
Stir together preserves and next 3 ingredients in a saucepan. Bring to a simmer over medium-low heat. Simmer, stirring occasionally, 2 minutes. Remove from heat, and reserve 1 1/2 cups. Brush remaining glaze over ham.
Bake at 325°, uncovered, on lowest oven rack 2 hours or until a meat thermometer inserted in thickest portion registers 140°, basting every 30 minutes with reserved 1 1/2 cups glaze. Let stand 15 minutes before serving.
