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

What each ingredient does

Haricot beans
Provide the main body and thickness once softened and sieved into the soup.
Milk
Adds creaminess and softens the soup's flavour when stirred in at the end.
Butter
Adds richness and carries flavour from the onion and celery seeds.
Onion
Contributes savoury aroma and sweetness as it cooks gently in the soup.

The step that matters

Boil gently for 3 hours. Beans must become fully soft before sieving; a hard boil can break the skins unevenly and stick to the pan, while undercooked beans leave a grainy, starchy texture that the sieve cannot fix.

Swap the beans

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

  1. Beansthe original
  2. Walnutfits about as well
  3. Sesamefits less well
  4. Black-eyed peafits less well

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