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

What each ingredient does

Potato
Starch that thickens the soup and gives it a smooth, full body when puréed.
Celery
Provides the main savoury, herbal flavour and some body to the soup.
Butter
Adds fat for a rounder mouthfeel and a richer finish.

The step that matters

Rubbing the mixture through a sieve. The vegetables must be cooked fully tender first, so they press through smoothly and give a silky texture instead of a grainy or stringy one.

Swap the celery

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

  1. Garlicfits better
  2. Parsleyfits better
  3. Thymefits better
  4. Celerythe original

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