Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Chicken Bouillon
Ingredients
Directions
Make the broth
Place the chicken in a large pot with cold water, celery, onion, and parsley.
Heat slowly on the back of the stove until it simmers.
Cook for 6 hours, skimming often.
Strain the broth and let it sit overnight.
Clarify and finish
Remove all fat from the surface.
Heat the broth and season with salt and pepper.
Beat the egg white with ½ cup of cold water and add it to the broth.
Wash the eggshell and add it to the broth, ensuring no yolk gets in.
Boil the broth rapidly for 10 minutes.
Add 1 cup of cold water and boil for 5 more minutes.
Serve in cups topped with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Its proteins coagulate as the broth heats, trapping cloudy particles so they can be strained out, clarifying the broth.
- Chicken
- Releases its flavor and gelatin into the water during long simmering, giving the broth its body and taste.
The step that matters
Boil the broth rapidly after adding the egg white. The egg white and shell must be given time to coagulate and rise with the impurities. Boiling too gently or stirring can leave the broth cloudy, and a yolk in the mix would add fat and prevent clarification.
Swap the onion
How well each one fits the dish's main ingredients (chicken, celery, parsley, pepper, egg, cream):
- Carrotfits better
- Spinachfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against chicken, celery, parsley, pepper, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
