 Dishes can either include the sauce as an ingredient in cooking or use the sauce as a pour-over or dipping sauce for the meal.Chinese restaurants in Western countries commonly serve chicken, pork, or shrimp that has been battered and deep-fried, then served with a sweet and sour sauce poured over the meat.It is also common to find the sweet and sour sauce cooked with sliced green peppers, onions and pineapple before it is poured over the meat.
