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 ↓
Celery Soup
Ingredients
Directions
Prepare the celery
Parboil the celery pieces in water for 5 minutes, then drain.
Make the soup
In a saucepan, melt 4 ounces of butter, then add the celery, salt, pepper, and white broth. Cover and simmer for 1 hour.
In another saucepan, knead 4 ounces of butter with 5 ounces of flour until combined.
Stir and cook the flour mixture briefly, then dilute it with 1 quart of boiled cream and 2 quarts of veal or chicken broth.
Add the cooked celery to the mixture and boil for 10 minutes.
Pass the soup through a sieve and return it to the heat.
Add 2 ounces of butter, 1 cup of raw cream, and 1 teaspoon of cream, stirring until combined.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 as it simmers and breaks down.
- Flour
- Cooked with butter to form a roux that thickens the broth.
- Butter
- Adds richness and fat, carrying flavour and giving a smooth mouthfeel.
- Cream
- Adds richness and a smooth, silky texture to the finished soup.
- Broth
- Forms the liquid base that the roux thickens and the celery cooks in.
The step that matters
Cooking the flour mixture briefly before adding the liquid. Flour must be cooked enough to lose its raw taste and to thicken smoothly; adding liquid too early or without stirring can leave lumps and a pasty flavour.
Swap the celery
How well each one fits the dish's main ingredients (butter, pepper, flour, cream, veal):
- Nutmegfits better
- Parsleyfits better
- Sagefits about as well
- Celerythe original
Fit is the average pairing score against butter, pepper, flour, cream, veal. Candidates are from the same food group and used in at least 100 recipes.
