1 tbsp. vegetable oil
4 pork chops, about 3/4-inch thick
salt and pepper
2 tbsp. grapefruit marmalade
1/2 cup grapefruit juice
1 tbsp. sherry vinegar
Heat oil in a 10-inch skillet over medium-high heat. Add chops, brown on both sides, seasoning with salt and pepper, five minutes. Drain off excess fat. Combine marmalade, grapefruit juice and vinegar in a small bowl, mixing well. Pour over chops. Cover, simmer 30 minutes or until chops are done. Remove chops to a warm platter.
Bring sauce to boiling; cook until slightly thickened, about five minutes. Spoon over chops just before serving.
