Chinese cuisine is famous for its rich umami flavor, and much of that depth comes from traditional fermented soybean seasonings.
Among the most commonly used are fermented soybean sauce (Douchi sauce), yellow soybean paste, and Doubanjiang (chili bean paste).
Although all three are made from soybeans, they are very different in ingredients, fermentation methods, flavor, and cooking uses.
Understanding the difference will help you cook authentic Chinese dishes at home.

- Using yellow bean paste instead of Doubanjiang will make Sichuan dishes lose flavor
To cook authentic Chinese food, always choose the correct fermented sauce.
