Also known as Xiang Cai, Hunan cuisine has already developed into a famous culinary school in China. Hunan dishes consist of local dishes from the Xiangjiang River area, Dongting Lake area and Western Hunan mountain area. Hunan’s culinary specialties are akin to those of the chili-rich Sichuan dishes. It is also characterized by thick and pungent flavor. Chili, pepper and shallot are usually necessaries in this division. However, Chili, peppers, garlic (suan) and an unusual sauce, called "strange-flavor" sauce (guai wei jiang) on some menus, enliven many dishes, with a somewhat drier intensity than that of their Sichuan counterparts. Sweetness, too, is a Hunan culinary passion, and honey sauces are favored in desserts such as water chestnut or cassia flower cakes.
