HEATING HAM SLICES IN OVEN RECIPES

Steps:

• Preheat oven to 400°. In a skillet, cook the onion and 2 tablespoons of the butter over moderately low heat, stirring, until it is very soft. In a heavy saucepan, melt 6 tablespoons of the remaining butter over moderately low heat, whisk in the flour, and cook the roux, whisking, for 3 minutes. Add the milk, scalded, in a stream, whisking, and bring the sauce to a boil. Simmer the sauce, whisking, for 1 minute and add salt and pepper to taste.
• Peel the potatoes and slice them ⅛-inch thick. Spread about one third of the sauce in the bottom of a well-buttered 3-quart gratin dish at least 2 ½-inches deep, cover it with a layer of potato slices, overlapping the slices slightly, and cover the potatoes with one third of the onions. Sprinkle the onions with one third of the Cheddar and continue to layer the remaining sauce, potatoes, onions, and Cheddar in the same manner. Sprinkle the top with bread crumbs, and dot it with the remaining 1 tablespoon butter, cut into bits.
• Bake the mixture, covered with foil, in the middle of preheated oven for 20 minutes. Remove the foil and bake the potato mixture for 35 minutes more, or until the top is golden and the potatoes are tender.

Steps:

• Heat the oven to 325 degrees F. 
• In a bowl, mix together the brown sugar, honey, orange zest, 1/4 cup orange juice, pumpkin pie spice, and nutmeg. Season with salt. 
• Roll out enough aluminum foil to surround the ham and place the ham in the center of the foil. Peel back the layers of the ham and place a sprig of thyme between every other layer of the spirals. Pour half of the glaze over the ham allowing it to sink into the slices. Tightly wrap the ham in the foil and place on a rack in a roasting pan. Fill the pan with an inch of water and roast in the oven until the internal temperature reaches 140 degrees F, about 20 minutes per pound. 
• Pour the remaining half of the glaze in a small saucepot on medium heat and bring to a simmer. Whisk until small bubbles appear all over, then turn off the heat. The glaze will thicken as it rests. 
• Raise the oven temperature to 400 degrees F. 
• Remove the ham from the oven. Using caution and tongs to help, peel back the aluminum foil from the top, leaving the aluminum foil on the sides and underneath the ham to catch the glaze and juices. Slather the remaining glaze all over the top of the ham and place back in the oven uncovered for 15 more minutes. Remove and let rest before slicing.
