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

What each ingredient does

Chestnuts
Provide the main body and starchy, creamy texture of the soup once pressed through a sieve.
Butter or drippings
Cook the onion gently and carry flavor through the soup base.
Flour
Thickens the soup as it cooks with the milk and chestnut mixture.
Milk
Adds richness and a smooth, creamy body to the soup.

The step that matters

Add flour, seasonings, and chestnut mixture to the onion. Flour must be cooked into the fat before liquid is added, or it stays raw-tasting and forms lumps. Cooking it briefly lets it thicken the soup smoothly.

Swap the celery

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

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

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