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
Make beef broth and skim off the fat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef broth
- Forms the liquid base that carries the flavor of the soup.
- All-purpose flour
- Thickens the broth into a smoother, more body-rich soup when made into a paste.
- Celery
- Provides the main vegetable body and flavor, softening as it boils in the broth.
- Heavy cream or butter
- Adds richness and a silkier mouthfeel to the finished soup.
The step that matters
Add the flour paste to the broth. Flour must be mixed smoothly with water first and stirred into hot broth; added dry or in lumps it clumps and leaves a grainy, uneven thickness. Flour starch thickens as it heats, so the soup should be simmered briefly after adding it.
Swap the celery
How well each one fits the dish's main ingredients (beef, flour, cream, pepper):
- Nutmegfits better
- Turmericfits about as well
- Celerythe original
- Tarragonfits about as well
Fit is the average pairing score against beef, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
