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

What each ingredient does

Celery
Provides the main flavour and body of the soup as it is mashed into the liquid.
Milk
Forms the creamy base of the soup and adds richness and mild sweetness.
Flour
Thickens the milk mixture so the soup becomes smooth and full-bodied.
Butter
Adds fat that carries flavour and gives the thickened base a richer mouthfeel.
Onion
Contributes savoury aroma and background flavour to the milk base.

The step that matters

Add the flour and butter to the milk mixture. Flour needs fat and heat to thicken smoothly; adding it without stirring or cooking it through can leave lumps and a raw, pasty taste.

Swap the onion

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

  1. Leekfits better
  2. Parsnipfits better
  3. Arrowrootfits better
  4. Onionthe original

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