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.

    Shared aroma: guaiacol (smoky, sweet).

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Celery
Forms the bulk of the soup and provides its main flavor and body.
Butter
Adds fat and richness, carrying flavor through the soup.
Flour
Thickens the soup by binding with the butter and absorbing liquid.
Broth
Supplies the liquid that cooks the celery into a soft, spoonable soup.
Crushed sugar
Adds a touch of sweetness that rounds out the celery flavor.

The step that matters

Stirring the flour into the melted butter. Cooking flour in fat before adding liquid coats the starch granules so they disperse evenly. Adding liquid too early or without enough stirring can leave lumps and an uneven thickness.

Swap the celery

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

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

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