Sweet pineapple with zingy tamarind makes for a beautifully lacquered holiday ham with just a few ingredients. Bonus: tamarind's natural acidity helps tenderize the meat, making for a juicy centerpiece.
Preheat oven to 300°F.
Wrap ham in aluminum foil, and place on a rimmed baking sheet. Bake until warmed through, about 1 1/2 to 2 hours. Pull back foil from ham.
Whisk together preserves, pineapple juice, tamarind paste, and pepper in a small bowl. Baste ham with one fourth of pine-apple preserves mixture. Bake ham, uncovered, basting with pineapple preserves mixture every 10 minutes, until glazed, about 30 minutes. Remove from oven, and let rest 5 minutes. Serve ham with any remaining pineapple preserves mixture.
