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, sweet flavour of the soup.
- Milk
- Forms the liquid base and gives the soup its creamy texture.
- Butter and flour
- Form a roux that thickens the milk into a smooth soup.
The step that matters
Stir the roux into the milk until boiling. Flour thickens only when it is fully mixed in and heated, so stirring keeps it from clumping and lets the starch swell evenly for a smooth soup.
Swap the white pepper
How well each one fits the dish's main ingredients (chestnut, milk, butter, flour, celery, onion):
- Cinnamonfits better
- Capersfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against chestnut, milk, butter, flour, celery, onion. Candidates are from the same food group and used in at least 100 recipes.
