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

What each ingredient does

Milk
Forms the creamy body of the soup once it is thickened.
Flour
Thickens the milk as it cooks, giving the soup body.
Butter
Adds richness and a smooth, rounded mouthfeel.
Celery
Provides the main vegetable flavor and, when mashed, the soup's texture.

The step that matters

Add the wet flour to the boiling milk. Flour clumps if added dry or to cold liquid. Wetting it with cold milk first lets it disperse, and adding it to boiling milk lets starch swell evenly into a smooth thickened base.

Swap the mace

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

  1. Parsleyfits better
  2. Thymefits better
  3. Turmericfits better
  4. Macethe original

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