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

What each ingredient does

Milk
Provides liquid and creaminess, setting the soup's body and consistency.
Butter
Adds fat and richness, carrying flavour and smoothing the texture.
Flour
Thickens the soup when creamed with butter and stirred in, giving body.

The step that matters

Adding the butter and flour mixture. Flour mixed with butter thickens the soup only when it is fully blended in and heated. Adding it in lumps or without cooking it through can leave a raw floury taste and uneven, grainy thickness.

Swap the onion

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

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

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