Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

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, and its fibres thicken the soup when pressed through a sieve.
- Milk
- Forms the creamy liquid base of the soup.
- Butter and flour
- Form a roux that thickens the soup as it cooks.
- Cream
- Adds richness and fat, giving the soup a smoother mouthfeel.
The step that matters
Add the butter and flour mixture to the hot milk and cook until thick. Flour thickens only when its starch granules are heated in liquid, and stirring prevents lumps. Cooking long enough lets the starch fully swell, so the soup reaches full thickness without a raw floury taste.
Swap the onion
How well each one fits the dish's main ingredients (celery, milk, butter, flour, pepper, cream):
- Potatofits better
- Leekfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against celery, milk, butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
