Suan Yu Zha Yu is a wonderful and rarely known dish among Tu and Miao Minorities. This food boasting unique local flavor is cooked by newly caught fish. After cleaning and washing the fresh fish, people would swathe the fish by rice powders. The rich powders are added salt before wrapping fish. Then the fish was kept in pot for 3-5 days. When the fish becomes a bit sour, it can be deep-fried into golden color. Such a kind of dish is vinegary and fragrant. As soon as you see the deep-fried Suan Yu Zha Yu, you will be full of mouth water. As the fish has been marinated by salt in pots, it is also edible without deep-frying. This food is appetitive and available in all four seasons.
