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
- Lean beef
- Releases flavor and gelatin into the broth as it simmers slowly over long cooking.
- Egg white and shell
- Coagulates as it heats, collecting fine particles so the broth clears.
- Celery
- Adds aromatic, savory flavor to the broth during long simmering.
- Onion
- Adds aromatic sweetness and savory depth to the broth.
The step that matters
Skim the surface when boiling briskly. Foam and fat rising to the surface can cloud the broth and give it an greasy taste, so removing them keeps the broth clear and clean-flavored.
Swap the onion
How well each one fits the dish's main ingredients (beef, celery, pepper, egg):
- Carrotfits better
- Capsicumfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against beef, celery, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
