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
- Forms the main body and flavour of the soup once cooked and pureed.
- Butter
- Melts with flour to form a roux that thickens the soup and adds richness.
- Flour
- Thickens the soup when cooked in butter to form a roux.
- Milk
- Adds liquid and creaminess, loosening the thickened puree to the desired consistency.
- Egg yolk
- Enriches the soup and adds body when stirred in off the heat.
- Cream
- Adds richness and smoothness to the finished soup.
The step that matters
Stir in the egg yolk and cream off the heat. Egg yolk thickens by setting when heated, so adding it to a boiling soup can curdle it. Removing the pan from the heat first lets it thicken gently and smoothly.
Swap the onion
How well each one fits the dish's main ingredients (celery, butter, flour, milk, pepper, egg, cream):
- Potatofits better
- Leekfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against celery, butter, flour, milk, pepper, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
