Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and body of the soup as it softens and releases its juices into the stock.
- Butter
- Carries flavour and, when melted with flour, forms the base that thickens the soup.
- Flour
- Thickens the stock into a smooth, velvety soup when cooked with the butter.
- Cream
- Adds richness and a smooth, mellow texture to the finished soup.
The step that matters
Stirring the flour into the butter. If the butter is browned or the flour is not mixed in smoothly, lumps and a darker, nutty taste can form. Stirring constantly over gentle heat and adding the stock gradually keeps the roux smooth so it thickens the soup evenly.
Swap the celery
How well each one fits the dish's main ingredients (butter, flour, cream):
- Nutmegfits better
- Jalapenofits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
