Red Bean Soup
This is a dish defined by the quality of the bean and the duration of the simmer. You are looking for a state where the skins are intact but the centers have surrendered completely to the heat.
Patience is your primary ingredient
Do not rush the softening process, or the beans will remain chalky. Use a heavy-bottomed pot to prevent the beans from catching and scorching on the base.
- Heavy-bottomed Dutch oven or stockpot
- Fine-mesh strainer
- Wooden spoon
What goes in.
- 1.5 cupsdried adzuki beans
- 6 cupswater
- 3/4 cuprock sugar or light brown sugar
- 1 pinchsea salt
- 2 slicesfresh ginger (optional)
Achieving the starch release
The goal is to cook the beans until they naturally break down and release their starches into the water, thickening the liquid into a creamy consistency without the need for external thickeners.
The method.
Rinse and soak
Rinse the beans under cold water. Cover with fresh water and let sit for at least 4 hours, or overnight, to ensure they soften evenly.
First boil
Drain the beans and add them to a pot with 6 cups of clean water. Bring to a rolling boil for 5 minutes, then drain again to remove the initial bitterness.
The long simmer
Add 6 cups of fresh water, the ginger slices, and bring to a gentle boil. Reduce heat to low, cover, and simmer for 90 minutes. Stir occasionally to prevent sticking.
Sweeten
Once the beans are soft enough to crush against the side of the pot with your spoon, stir in the sugar and salt. Continue simmering for another 20 minutes until the sugar has fully dissolved and the soup reaches your desired thickness.
Other turns to take.
With Sticky Rice Balls
Add cooked glutinous rice balls (tangyuan) to the finished soup right before serving for a chewy contrast.
Citrus Infusion
Add a strip of dried tangerine peel during the final 30 minutes of simmering for a bright, aromatic undertone.
When it doesn't go to plan.
Test the beans by pressing one against the side of the pot; if it meets resistance, it needs more time.
If the water level drops too low before the beans are soft, add boiling water in small increments.
The soup will thicken further as it cools; adjust the consistency with a splash of water if you prefer it thinner.

Can I use a pressure cooker?
Yes. Use 4 cups of water instead of 6 and cook on high pressure for 20 minutes with a natural release. Finish by simmering on the stovetop to adjust the sugar and thickness.
Why did my beans stay hard?
The age of the beans determines the cooking time. If they are older, they may require a longer soak or an additional hour of simmering.
