Earthen pot soup is the pride of Nanchang cooking and has a history of more than 1,400 years. This tradition dates back to the Tang Dynasty, when people used clay pots to simmer soup over charcoal. The secret is the sealed cooking environment - no steam escapes, so all the flavors and nutrients are retained. In old Nanchang, there are many clay pot soup shops, each with its own charcoal fire and rows of clay pots. The best crock pot soup takes 7-8 hours to cook, and the soup is clear but rich in flavor. This dish has been designated as an intangible cultural heritage of Jiangxi Province.
