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 Broth
Ingredients
Directions
Make the broth
Place half a chicken in a stewpan with water, leek, celery, salt, and parsley.
Bring to a boil, skim thoroughly, and let it simmer for 1 hour.
Strain the broth through a sieve.
Thicken and finish
Return the broth to the stewpan and heat over the fire.
Moisten the flour with a little cold broth or water until smooth.
Pour the flour mixture into the boiling broth while stirring quickly.
Let it simmer for 15 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Releases flavor and gelatin into the water, giving the broth body and savory depth.
- Flour
- Starch that thickens the broth slightly when heated in liquid, giving it a fuller texture.
The step that matters
Pouring the flour mixture into the broth. Flour clumps if added dry or unevenly. Moistening it first and stirring quickly into boiling broth disperses the starch so it thickens smoothly instead of forming lumps.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, leek, celery, flour):
- Thymefits better
- Turmericfits about as well
- Tarragonfits about as well
- Parsleythe original
Fit is the average pairing score against chicken, leek, celery, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
