The sweet-and-sour taste is widespread in both oriental and Western cuisine. In the East, we think of the sweet and sour sauces of Chinese cuisine. In the West, we find the famous American barbecue sauce. Even in Italy the sweet-and-sour taste is pleasing, though not one of the fundamental flavours of Mediterranean cuisine.
