Red Bean Soup (Hong Dou Tang / 红豆汤)
Cantonese and Jiangnan tradition — ubiquitous across southern China
Classic Chinese dessert soup of azuki red beans slow-cooked in water with rock sugar, dried tangerine peel, and sometimes lotus seeds or lily bulb until beans are tender but intact. Served hot in winter or chilled in summer. One of the most beloved Chinese sweet soups across Cantonese, Shanghainese, and Taiwanese traditions.
