The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Celery
Provides the main flavor and body of the soup as it softens in the water.
Rich milk
Adds creaminess and a smooth, rich texture to the soup.
Flour
Thickens the soup as it is stirred in with milk and heated.
Butter
Adds fat for richness and a smoother mouthfeel.

The step that matters

Stirring the thickening into the soup. Flour clumps if added dry or without being mixed smooth first. Mixing it with a little milk, then stirring it in fully, lets the starch disperse evenly so the soup thickens without lumps.

Swap the celery

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

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

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