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 of the soup once pounded and cooked.
- Milk
- Forms the liquid base that the celery simmers in, giving the soup its creamy body.
- Butter
- Adds richness and fat, and helps form the roux with the flour.
- Flour
- Thickens the sauce by forming a roux with the melted butter.
- Cream
- Adds richness and a smoother, silkier texture to the sauce.
The step that matters
Gradually adding the cream to the roux. Adding liquid slowly while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (celery, milk, butter, flour, cream, pepper):
- Potatofits better

- Onionthe original
Fit is the average pairing score against celery, milk, butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
