Douchi (Chinese: 豆豉; pinyin: dòuchǐ) is a special kind of soybean product. It is also known as fermented black soybeans or Chinese fermented black beans. People make it by fermenting and salting black soybeans. This food is very popular in Chinese cooking. It is often used to create delicious black bean sauce dishes.
To make douchi, black soybeans are fermented and salted. This process makes the beans soft and usually semi-dry. Sometimes, regular white soybeans are used too. But these turn brown and are called mianchi. Douchi has a strong, spicy smell. Its taste is salty, a little bitter, and slightly sweet.
It's important not to confuse douchi with black turtle beans. Black turtle beans are a different type of bean. They are often used in the foods of Central America, South America, and the Caribbean.

Ancient Discoveries
In 165 BCE, archaeologists found douchi in a tomb in South Central China. This tomb, called Han Tomb No. 1 at Mawangdui Tomb Site, was sealed around 165 BCE. It was first opened in 1972. The tomb belonged to a high-ranking woman. The discovery showed that douchi was an important food even back then.
Douchi in Ancient Texts
Around 90 BCE, a famous book called Records of the Grand Historian mentioned shi. This was another name for salty fermented soybeans. The book showed that douchi was a valuable item in China.
