Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Squash
- Forms the thick body and main flavour of the soup once rubbed smooth.
- Butter
- Adds fat and richness, and carries the onion flavour when melted.
- Flour
- Thickens the liquid so the soup becomes smooth and body-rich.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
The step that matters
Scald the cream before beating it in. Scalding warms the cream so it blends in smoothly instead of cooling the soup or curdling when added to hot liquid.
Swap the mace
How well each one fits the dish's main ingredients (butter, onion, pepper, celery, clove, flour, cream):
- Nutmegfits better
- Parsleyfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against butter, onion, pepper, celery, clove, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
