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 ↓
Delicate Celery Soup
Ingredients
Directions
Cook the celery
Break the celery stalks into pieces and pound the celery pieces in a wooden bowl.
Add the pounded celery to the onion and milk in a double boiler and cook for 20 minutes.
Make the roux and finish
Melt the butter in a separate pan and cook the flour and seasonings in the melted butter.
Add the cream and stir until it thickens and boils.
Stir the thickened mixture into the celery and milk.

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 aroma of the soup.
- Milk
- Forms the liquid base of the soup and carries the celery flavour.
- Butter
- Adds richness and fat, and helps form the roux with the flour.
- Flour
- Thickens the soup when cooked in butter and stirred in.
- Cream
- Adds richness and body to the finished soup.
The step that matters
Stir the thickened mixture into the celery and milk. Flour thickens only when starch granules swell in hot liquid, so the roux should be smooth and stirred in gently while the soup is hot to avoid lumps and a pasty texture.
Swap the onion
How well each one fits the dish's main ingredients (celery, milk, butter, flour, pepper, cream):

- 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.
