To commence the cooking process, preheat your oven to oven to 165℃ (325℉).
While the oven is heating up, prepare your glaze by combining 1 cup brown sugar, ½ cup pineapple juice, ¼ cup Dijon mustard, ¼ teaspoon ground cloves, ½ teaspoon ground nutmeg and 1 teaspoon ground cinnamon in a saucepan over medium heat.
Stir gently until all ingredients are well combined and bring it to a gentle simmer.
Next step involves scoring the surface of your 1 fully-cooked bone-in ham in diamond-shaped patterns using a sharp knife.
Place your scored ham on a roasting rack within a roasting pan and Baste it generously with some of the prepared glaze mixture.
Reserve some glaze for later use during cooking.
Cover your ham loosely with aluminum foil and place it in the preheated oven. Allow it to cook for 1 hour, or until the ham is heated through and the glaze is thickened.
About halfway through cooking time, remove the foil and brush another layer of glaze onto the surface of your ham.
While cooking continues, periodically baste your ham with additional glaze every 20 minutes or so to ensure optimal flavour infusion.
The final result should be an enticingly golden-brown glazed crust enveloping succulent slices of tender Christmas ham.
Once fully cooked, remove your ham from the oven and let it rest for a few minutes before carving.
The resting period will allow the juices to redistribute, resulting in a juicy and flavourful experience.
Serve your classic glazed Christmas ham with brown sugar and pineapple glaze as a centrepiece to your festive spread, accompanied by traditional holiday sides such as roasted vegetables, mashed potatoes, or cranberry sauce.
This timeless dish is sure to be savoured by all, creating lasting memories of joyous celebrations during this special time of year.
