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.
- Milk
- Forms the liquid base and adds creaminess.
- Flour
- Thickens the soup as it cooks, giving it a smoother body.
- Butter
- Adds richness and carries flavour in the thickening step.
- Whipped cream
- Adds richness and a light, silky texture when stirred in at the end.
The step that matters
Mix flour and butter until smooth before stirring into the soup. Flour clumps if added dry or unevenly to hot liquid. Blending it smoothly with fat first lets the starch disperse and thicken the soup evenly.
Swap the celery
How well each one fits the dish's main ingredients (milk, flour, butter, onion, cream):
- Nutmegfits better
- Garlicfits better
- Cinnamonfits better
- Celerythe original
Fit is the average pairing score against milk, flour, butter, onion, cream. Candidates are from the same food group and used in at least 100 recipes.
