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

What each ingredient does

Shelled peanuts
Provide the main body and nutty flavour once cooked soft and sieved.
Flour
Thickens the liquid so the soup becomes smooth and creamy.
Butter
Adds richness and helps the flour blend smoothly into the soup.
Chicken stock or milk
Supplies liquid and savoury depth, and adds creaminess when milk is used.

The step that matters

Thicken with flour and butter mixed together. Flour added directly to hot liquid clumps, so it should be blended with the butter first. Cooking it briefly lets the starch swell and thicken the soup evenly.

Swap the peanut

How well each one fits the dish's main ingredients (onion, celery, chicken, flour, butter, pepper):

  1. Beansfits better
  2. Black-eyed peafits better
  3. Cashew nutfits better
  4. Peanutthe original

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