Ingredients

Directions

Prepare the beans

  1. Soak the black beans overnight, then drain.

  2. Add the parsley, celery root, bay leaf, peppercorns, clove, and onion tied in cheesecloth, cover with cold water, and boil slowly until tender, adding water as needed.

  3. Once the beans are soft, remove the seasonings and pass the beans through a sieve, mashing them with a spoon.

Make the soup

  1. Add the soup stock to the mashed beans.

  2. Melt the butter, stir in the flour, and gradually mix into the stock.

  3. Season with salt and pepper.

Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Black beans
Form the body of the soup once softened and sieved into a thick purée.
Butter
Enriches the soup with fat and a rounder, smoother mouthfeel.
Flour
Thickens the stock when cooked in butter and mixed in, giving the soup more body.
Soup stock
Supplies the liquid base that thins the bean purée into soup.
Sherry wine
Adds acidity and a mellow, aromatic note to the finished soup.

The step that matters

Mixing the butter and flour into the stock. If flour is added without first cooking it in the melted butter, or stirred in too quickly, it clumps and leaves lumps. Mixing gradually into the stock keeps the thickening smooth.

Swap the onion
