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 ↓
Chicken Bouillon
Ingredients
Directions
Make the broth
Place the chicken pieces in a large pot with the cold water.
Bring to a boil slowly, then simmer gently for 3 hours until the meat is tender.
Add the sliced onion and celery, and simmer for an additional hour.
Chill and strain
Transfer the broth to a bowl and chill for several hours.
Once chilled, remove the fat from the surface and strain out the bones.
If the broth is jellied, heat it gently to melt the jelly.
Strain the broth through coarse muslin without squeezing the bag.
Clarify and season
Heat the strained broth until lukewarm, then add the unbeaten egg white and broken shell.
Stir to a quick boil and strain again through muslin, seasoning to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Gives the broth its meaty flavor and body as it simmers.
- Egg white
- Its proteins coagulate and trap cloudy particles, clarifying the broth.
- Egg shell
- Adds fine particles that help catch impurities when the broth is clarified.
- Celery
- Adds aromatic flavor to the broth during the final simmer.
- Onion
- Adds aromatic sweetness and savory depth to the broth.
The step that matters
Stirring the egg white into the broth and bringing it to a quick boil. Egg white proteins must be whisked into the lukewarm broth before heating so they rise and trap cloudy particles. Stirring too gently or boiling too long can leave the broth cloudy or let the proteins break apart and cloud it again.
Swap the onion
