Orange-Glazed Pork Chops (Mccall'S Cooking School)

Preheat oven to 375°F Wipe pork chops with damp paper towels. With a sharp utility knife, make a lengthwise cut in the fat edge of each chop, about 3 inches long, cutting through all the way to the bone, to form a pocket. Or ask your butcher to cut a pocket when purchasing the chops.
In a large skillet, melt butter. Add celery and onion and cook, stirring occasionally, until celery is tender, about 8 minutes. Add bread cubes and cook until lightly browned, stirring constantly. Remove skillet from heat.
Into skillet, sprinkle 3 tablespoons orange juice, the parsley, 1/2 teaspoon salt and orange peel. Toss mixture lightly to combine. Fill pockets of chops with stuffing mixture, using your finger to force stuffing towards the bone.
Arrange chops on a rack in a 13-by-9-by-3 inch roasting pan, standing chops on rib bones. Sprinkle with remaining salt. Pour 1 1/2 cups orange juice into roasting pan (the juice should not touch the rack). Loosely cover chops and pan with foil. Bake 45 minutes.
Meanwhile, make the glaze. In small saucepan, combine 1/2 cup orange juice, sugar, marmalade and vinegar. Stir over medium heat until mixture is smooth and comes to a boil Reduce heat and simmer, uncovered, 15 minutes, stirring occasionally.
Remove foil from roasting pan. Brush chops with some of the glaze. Bake, uncovered, 45 to 50 minutes, or until chops are tender and golden brown, basting with glaze every 10 minutes. Brush with remaining glaze before serving. Makes 4 servings.
