Green-Core Black Bean, Goji Berry and Red Date Soup (Qing Ren Hei Dou Soup)

Why people make this soup

In traditional Chinese food therapy, black is the colour associated with the kidneys, and black beans have been eaten for centuries as a nourishing food for kidney health. But not all black beans are used the same way — the variety that keeps coming up in classical food-therapy texts is the “green-core” black bean (qing ren hei dou), which has green flesh inside its black skin rather than the yellow flesh of common black beans. Nourilo has checked multiple food-therapy references and they consistently specify this green-core variety for therapeutic use, so when shopping, look for the one with green insides.

When kidney vitality is well supported, traditional thinking says a number of things follow: stronger hair, clearer vision, a brighter complexion, and better energy overall. This soup is a straightforward way to incorporate that idea into everyday cooking — three simple ingredients, naturally sweet, no meat required.

Method

1. Soak and rinse the black beans. Rinse the goji berries gently. Pit and rinse the red dates.
2. Place the black beans and red dates into a pot with 1.8 L of water. Bring to a boil, then reduce to a medium-low simmer and cook for about 1 hour.
3. Add the goji berries and continue to simmer for a further 10 minutes.
4. Serve warm, eating both the soup and all the ingredients.

Nourilo’s Tips

Keep the bean skins on — they hold some of the most valuable compounds. When buying goji berries, choose ones that still have the small yellow-white stem scar at the tip, as this indicates they have not been artificially coloured. For red dates, Xinjiang jujubes with stones (stone rattles inside when shaken) are the most nourishing. Roasted black beans are more warming in nature — good for elderly people with frequent nighttime urination or tinnitus — but those who run hot or children should stick to the unroasted version in this recipe.
