- Cooking: 1 hour
- Total Time: 1 hour 15 minutes
Yield
Serves 4-6 people
Difficulty level
Easy to Medium – Perfect for home cooks willing to embrace traditional ingredients
Ingredients
- 1 cup dried red beans (adzuki beans), rinsed and soaked for 4 hours
- 6 cups water
- 1/2 cup rock sugar or granulated sugar (adjust to taste)
- 1 piece dried tangerine peel (optional, about 1-inch square), rinsed
- 1/4 teaspoon salt
- 1/2 teaspoon vanilla extract (optional, for a subtle aroma)
- 1 teaspoon glutinous rice balls or cooked tapioca pearls (optional garnish)
instructions
- Drain the soaked red beans and place them in a large pot with 6 cups of fresh water.
- Bring to a boil</b over high heat,then immediatly reduce to medium-low heat. Skim off any foam on the surface to keep the broth clear and clean.
- Add the dried tangerine peel (if using) and cover the pot partially; simmer gently for about 45 to 60 minutes, stirring occasionally, until the beans are very soft and beginning to break apart.
- Stir in rock sugar and salt, adjusting sweetness to your preference. Continue simmering for another 10 minutes so the sugar dissolves thoroughly and the flavors meld.
- remove tangerine peel before serving. For a smooth consistency, you may mash some beans gently with the back of a spoon.
- If desired, add cooked glutinous rice balls or tapioca pearls for a textural contrast and sweetness enhancement.
- Serve warm, garnished with a few whole beans or a sprinkle of toasted sesame seeds for an inviting finish.
Tips for Success
- Soaking the beans reduces cooking time and helps develop a creamy texture – don’t skip this step!
- Rock sugar offers a subtle, mellow sweetness and a glossy finish, but brown sugar or honey can be used as creative alternatives.
- For a richer version, simmer with coconut milk added just before serving to introduce a luscious, tropical layer.
- When using dried tangerine peel, ensure to rinse well to avoid bitterness but retain the aromatic floral notes.
- Leftover soup stores well in the fridge for up to 3 days and tastes even better after the flavors meld overnight.
Serving Suggestions
Serve Hong Dou Tang in charming ceramic bowls at room temperature or slightly warmed-ideal as a winter comfort dessert or a refreshing summer treat when chilled. Garnish with a drizzle of coconut cream, a sprinkle of toasted sesame seeds, or a couple of chewy glutinous rice balls for enhanced texture and authenticity. Pair it beautifully with light jasmine tea or green tea to balance the sweetness and cleanse the palate.
