Black-bean Soup

Ingredients

Directions

Prepare the beans

  1. Soak two cupfuls of black beans overnight.

  2. Put the soaked beans into a saucepan with a bouquet of herbs, and cover them with cold water.

  3. Let them boil slowly until tender, adding more water if necessary.

  4. When the beans are very soft, remove the bouquet, drain off the water, and pass the beans through a puree sieve.

  5. Add to the pulp enough brown stock to make a soup of the consistency of thin cream.

Finish the soup

  1. Place the soup again on the fire and add a brown roux made of one tablespoonful of butter and one tablespoonful of flour, cooked together until brown; dilute it to smoothness before adding and cook it with the soup for five minutes.

  2. Season with salt and pepper.

  3. Strain the soup through a sieve into the tureen.

Garnish and serve

  1. Add thin slices of lemon, egg balls, and force‑meat balls, allowing one of each to each portion of soup.

  2. Add also the white of one hard‑boiled egg cut into small dice, and one quarter of a cupful of sherry or red wine.

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 pureed into a thick base.
Butter
Enriches the roux that thickens the soup and adds richness.
Flour
Thickens the soup with the butter as a roux, giving smoothness and body.
Brown stock (in the method)
Thins the bean puree to a soup consistency and adds savoury depth.
Sherry
Adds aroma and a touch of sweetness and acidity to the finished soup.

The step that matters

Adding the brown roux. Flour must be cooked in the butter until brown and fully diluted before it goes into the soup. Cooking out the raw starch avoids a pasty taste, and diluting it smoothly prevents lumps while the soup thickens.

Swap the onion

How well each one fits the dish's main ingredients (beans, sherry, butter, parsley, thyme, clove, flour):
