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, once pressed, the body of the soup.
Milk
Forms the creamy base of the soup.
Butter
Adds richness and fat to the soup.
Flour
Thickens the soup once stirred into the hot liquid.
Onion
Adds savoury aroma to the soup.

The step that matters

Stirring the butter and flour into the boiling soup. Flour starch swells and thickens when heated, but if it is added in clumps it forms lumps that do not smooth out. Rubbing the butter and flour together first and stirring constantly as it goes in keeps the starch evenly dispersed so the soup thickens smoothly.

Swap the onion

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

  1. Carrotfits better
  2. Potatofits better
  3. Capsicumfits better
  4. Onionthe original

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