Du'an Yao goat soup, with its distinctive white color and tender mutton, is one of the most famous specialties of Hechi's Du'an Yao autonomous county.

The main ingredients are bones and meat from a black goat raised in the county's mountains. The ingredients are cooked in a large pan of clear water with special seasonings. The liquid is then kept boiling until it turns white, while the mutton is infused with flavors while it cooks.
