Dr. Pepper-Pineapple Glazed Easter Ham

Preheat oven to 350°. Score ham in a diamond pattern and dot with cloves, then transfer to a roasting pan and cover loosely with foil. Bake until warmed through, 2 1/2 to 3 hours. During the last 10 minutes of cooking, heat Dr. Pepper, pineapple juice, brown sugar, and mustard in a small saucepan over medium heat and cook until reduced by half. Remove foil from ham and brush all over with glaze. Continue glazing ham every 10 minutes until caramelized and shiny. Remove ham from oven and let rest, 15 minutes, then slice. Serve with pineapples.
