(6 pound) fully-cooked, bone-in ham
(6 ounce) cans pineapple juice
Directions Preheat oven to 325 degrees F (165 degrees C). Place the ham, cut side down, into a roasting pan. Cut the skin off the pineapple with a sharp knife and cut out any brown spots of skin left behind. Slice the pineapple into 1/2-inch slices and cut the cores out of the slices. Pin the slices onto the ham with toothpicks. Bake ham in the preheated oven until a meat thermometer inserted into the thickest part of the ham reads 140 degrees F (60 degrees C), 1 1/2 to 2 hours. While the ham is baking, mix the pineapple juice and brown sugar in a microwave-safe ceramic or glass bowl and microwave on medium power until the glaze is boiling and slightly thickened. Work carefully because the glaze will be sticky and very hot. Pour about half the glaze evenly over the ham and pineapple about 1 hour before the end of baking; pour the rest over the ham about 30 minutes before the end of baking Although ham is perfectly delicious all by itself, you can make it extra-special by using a glaze. The most popular glaze recipes contain combinations of fruit juice, wine or whiskey, honey, mustard, brown sugar, fruit preserves, and spices. Brush some of the glaze over the surface of the ham before placing it in the oven. For a ham that has only been partially cooked, you will need to allow about 20 minutes per pound in a moderate (350 degrees F/175 degrees C) oven. A fully cooked ham will require about 10 minutes per pound in order to be heated all the way through. To help keep your ham moist and juicy: Place the ham cut-side down in a baking pan. If it's going to be in the oven for more than an hour, you also may want to place a foil "tent" over your ham in order to keep it from drying out. Continue to brush the ham with glaze and baste it with the pan juices every 20 minutes or so, until it is heated through. To finish the ham and give it a deliciously caramelized coating, remove the foil tent, brush it with glaze and pan juices one more time, then turn your oven to the broiler setting. Allow the outside of the ham to get nice and browned-this should only take about 5 minutes, but watch it closely so it doesn't get too dark. When the internal temperature reaches 160 degrees F (80 degrees C), the ham is ready for serving.
