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

What each ingredient does

Small white haricots
Provide the main body and thickening starch that makes the soup creamy after sieving.
Milk
Adds richness and a smooth, mellow body to the finished soup.
Leek
Contributes a mild onion-like aroma and savoury flavour as it softens during simmering.
Onion
Builds savoury depth and aroma as it cooks down into the broth.
Celery
Adds a fresh, aromatic background flavour to the simmered broth.

The step that matters

Passing the mixture through a wire sieve. Beans and softened vegetables must be pushed through fully so the soup becomes smooth and thickened; skipping or rushing this leaves a grainy, thin texture with skins and fibres still present.

Swap the celery

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

  1. Garlicfits better
  2. Thymefits about as well
  3. Celerythe original
  4. Capersfits about as well

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