Island Simmered Pork

6 servings. Place pork loin or butt in a 5-quart kettle. In a bowl, mix together vinegar, soy sauce, brown sugar and ginger. Pour over pork, cover and simmer approximately 3 hours or until pork is tender when pierced with a fork. You can double all the ingredients except the pork for more sauce. You can leave it thin or thicken the sauce with a little cornstarch for more of a gravy effect. Serve this with hot rice. A combination of steamed pineapple chunks, carrots, green peppers, and onions on the side is outstanding!
