What Is Fermented Bean Paste?– Detailed Answer

Fermented bean paste is commonly made from ground soy or broad beans. Fermenting soy or ground beans is a traditional food preparation method common in the South, east, and Southeast Asia communities. The fermented bean paste is not consumed by itself but is used to flavor food and produces a savory and salty taste in foods such as soups, stew, and stir-fries. The common colors of fermented bean paste include dark brown, reddish brown, and light tan. The color difference may be due to the production process and adding ingredients such as bacteria, sugar, rice, pasteurized mantou, and wheat flour. Roasting the beans before grounding and the age of the beans also contribute to the color of the paste. This article will describe the Chinese fermented bean paste, preparation, eating, and storage.       

Chinese fermented bean paste

 Doubanjiang

Doubanjiang is one of the several varieties of Chinese bean paste and has other names such as fermented chili bean paste, broad bean chili sauce, Toban-djan, or douban. As some of the names indicate, the bean paste has a savory and hot flavor. The major ingredients in making the paste include flour, salt, soybeans, chili peppers, and broad beans. The chili peppers contribute to the hot flavor. The paste is commonly used in flavoring Sichuan dishes such as Shuizhu, Huo Guo, and mapo tofu. Doubanjiang has several varieties, but the most common is the Pixian doubanjiang, which takes more than three years to ferment.   

Douchi

Douchi or tochi is also known as black beans, salty black beans, salted black beans, Chinese fermented black beans, or fermented black soybeans. It is a Chinese fermented bean paste made using salted black soybeans. It is mostly used in making dishes that use black bean sauce. The color of the paste is usually black because of the color of the beans used. The paste is mainly used in stir-fried flavoring vegetables such as leaf vegetables, bitter melon, and fish. Due to its high salt content, douche should not be consumed in large amounts and is only used for seasoning.     

 Dajiang

Dajiang is a fermented bean paste made from brine and soybeans. The production process involves soaking the soybeans in water overnight, boiling them in salty water, grounding them in a millstone, or using mortar. The resulting paste is shaped into cubes and dried in the shade for two to three weeks or until they are firm. The dried cubes are then tied with rice straw and placed in a warm room for fermentation. After fermentation, they are washed, sun-dried, and aged in brine before charcoal and chilies are added, and the paste can be eaten raw or used for flavoring vegetables.  

Tianmianjiang

Tianmianjiang is also known as sweet wheat paste, sweet flour sauce, or sweet bean sauce and is smooth and thick. It is commonly black or dark brown because the beans used in its preparation are black and because of the fermentation process. Although it is categorized as a bean paste, flour is the major ingredient in its preparation. One portion of soybeans is used for every 19 portions of flour. The fermentation process is kick-started by dried and stale steamed bread wrapped in miangua and placed in the dark until it is completely dry. It is used as a sauce for common Chinese dishes. Unlike many sauces, it is sweet.   

Huangjiang (yellow soybean paste)

The major ingredients for this fermented paste include wheat flour, water, salt, and yellow soybeans. The paste is black, dark brown, or light brown. It is commonly used in northern China as well as in Beijing cuisines. It is commonly used in fried sauce noodles prepared by frying ground pork with soybean paste and then pour the mixture on thick wheat flour noodles. The yellow soybean paste is no longer viewed as a traditional food because it is currently manufactured and packaged for use in modern cuisines across the globe.
