Red Bean Soup with Tangerine Peel — velvety sweet adzuki bean soup with sago pearls

Red bean soup, or hong dou sha, is the dessert soup of Cantonese childhoods, sweet adzuki beans simmered until they collapse into a velvet purée. A strip of dried tangerine peel lends a quiet citrus note, and lotus seeds add a gentle nuttiness. Served warm in winter and chilled in summer, it is the taste of tong sui shops and grandmothers’ kitchens alike, and the traditional ending to a banquet meal. Soak the beans overnight to shorten the simmer.

Velvety, sweet, and gently perfumed

The beans should cook down until the soup is thick and silky, with a few whole beans left for texture, sweetened with rock sugar rather than plain sugar for a cleaner finish. The tangerine peel is subtle — just enough to make you wonder what that brightness is. A swirl of coconut milk or a scoop of sago makes it a proper dessert, and a bowl of it, warm or cold, always lands like a comfort.

Step by stepInstructions

  1. Soak the red beans overnight; drain. Soak the tangerine peel in hot water for 30 minutes; scrape off any white pith.
  2. Combine the beans, tangerine peel, lotus seeds, and water in a large pot. Bring to a boil, then simmer partially covered for 1 hour 15 minutes, stirring occasionally.
  3. Meanwhile, boil the sago in plenty of water for 10 minutes; drain and rinse under cold water.
  4. When the beans are soft and starting to break down, stir in the rock sugar and salt and cook 15 minutes more, mashing some beans against the pot for body.
  5. Stir in the sago. Serve warm or chilled, with a swirl of coconut milk if you like.

💡 Chef tips & storage

Soaking the beans overnight halves the cooking time — don't skip it. Rock sugar gives a cleaner sweetness than white sugar; add it near the end and taste as you go.
