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

What each ingredient does

Butter
Enriches the soup and adds richness and a smooth mouthfeel.
Flour
Thickens the liquid into a smooth, creamy body when stirred into the boiling mixture.
Milk
Adds creaminess and mild sweetness, softening the soup's body.
Reserved celery liquid
Carries the celery flavor and forms the soup's base liquid.

The step that matters

Stir the butter and flour into the boiling mixture. Flour thickens only when its starch is dispersed and heated in liquid. Adding the blended paste to boiling liquid while stirring prevents lumps, since unstirred flour clumps into raw pockets that stay grainy and pasty.

Swap the celery

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Celerythe original

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