Douzhi is a traditional fermented mung bean juice that has been consumed in Beijing for centuries. It is made by soaking mung beans, grinding them into a paste, and fermenting the paste with water and a starter culture. The resulting beverage has a slightly sour and tangy taste. Douzhi is often served with fried dough sticks (youtiao) or steamed buns (mantou) for breakfast. It is an acquired taste but worth trying for a truly authentic Beijing experience.
