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

What each ingredient does

Leeks
Provide the main soft, mild onion flavor and body as they cook down.
Sour cream
Adds richness and a smooth, creamy texture to the finished soup.
Butter
Carries the slow cooking of the vegetables and adds richness and flavor.
Chicken broth
Forms the liquid base that cooks the vegetables and carries the soup's flavor.

The step that matters

Stir in the sour cream gently. Sour cream is prone to curdling or separating when it gets too hot or is stirred hard. Stirring gently, and off a hard boil, keeps it smooth and evenly blended.

Swap the celery

How well each one fits the dish's main ingredients (chicken, leek, onion, cream, butter, pepper):

  1. Garlicfits better
  2. Thymefits about as well
  3. Celerythe original
  4. Parsleyfits about as well

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