Cream of Bean Soup

Ingredients

Directions

Prepare the beans

  1. Soak the beans overnight.

Cook and mash

  1. Boil the beans in slightly salted water until very soft, leaving about 3 cups of liquid.

  2. Remove from heat, strain through a colander, and mash to a paste.

Finish the soup

  1. Return the mashed beans to the pot, add milk, butter, salt, and pepper.

  2. If the soup is not thick enough, mix flour with a little cold water and add it to the soup.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Beans
Form the body of the soup once cooked and mashed into a paste.
Milk
Adds creaminess and a softer, rounder flavour to the soup.
Butter
Adds fat, richness and a smooth mouthfeel to the soup.
Flour
Thickens the soup if it is not thick enough after mashing.

The step that matters

Adding the flour mixture. Flour must be mixed with cold water first so it disperses without lumps. Added dry or to hot liquid, it clumps, and the starch only thickens fully once the soup is heated enough to gelatinise it.

Swap the beans

How well each one fits the dish's main ingredients (milk, egg, butter, pepper, flour):

  1. Almondfits better
  2. Walnutfits better
  3. Milletfits about as well
  4. Beansthe original

Fit is the average pairing score against milk, egg, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
