"We’ve come to know sweet and sour Chinese-style dishes in two basic forms. As a stir fry, floured thin strips of pork or fish are tossed with sweet and sour sauce and some vegetables (often, just added for color). Or the dish can consist of a whole fish that had been deep fried until crisp, laid on a platter, smothered with sweet and sour sauce and topped with finely sliced vegetables." - imabonehead from Bookmarklet
