1. In a small bowl, combine the first seven ingredients. Pour a scant 1/2 cup into a large resealable plastic bag; add pork chops. Seal bag and turn to coat; refrigerate for 8 hours or overnight. Cover and refrigerate remaining marinade for sauce.
2. Drain and discard marinade. Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Grill chops, covered, over medium heat or broil 4-5 in. from the heat for 4-5 minutes on each side or until a thermometer reads 145°. Let stand for 5 minutes before serving.
3. Meanwhile, in a small saucepan, combine cornstarch and reserved marinade. Bring to a boil; cook and stir for 1 minute or until thickened. Serve with chops. Yield: 2 servings.
