Shaanxi cuisine is derived from the native cooking styles of northwestern China with elaborate use of ordinary materials, featuring strong flavor and heavy taste. The most famous dishes must be the pork and lamb and mutton. Shaanxi cuisine focuses on the using of the savory flavors such as salt, garlic, onion, and vinegar, however, sugar is seldom used. The main cooling methods are the steaming, frying, and stir-frying. Besides, since Shaanxi cuisine has been influenced by the flavors of the provinces of Shanxi and Sichuan, so the taste of Shaanxi cuisine is both sour and spicy, and a little salty. No doubt the noodles are the staple food, featuring wider, thicker, and longer.
