Oven-Barbecued Pork Chops

In a shallow bowl combine soy sauce, 1 cup water, 1/2 cup brown sugar, molasses and salt; mix well. Add pork chops, turn to coat, then cover and marinate overnight in the refrigerator. Preheat oven to 350 °F (175°C). Remove pork chops from the marinade and place in a 13 x 9 x 2-inch baking pan. Cover with aluminum foil and bake 1 1/2 hours. While pork chops are cooking; in a saucepan, combine remaining brown sugar and water, ketchup, chili sauce and dry mustard. Bring to a boil, stirring constantly. Pour over the pork chops and bake, uncovered, an additional 20 to 25 minutes. Serve hot.
