Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken or bones with meat
- Releases gelatin and flavor into the water, giving the stock body and depth.
- Lean meat
- Adds savory meat flavor to the liquid during the long simmer.
- Water
- Acts as the solvent that extracts flavor and gelatin from the bones and meat.
- Onion
- Contributes sweetness and aromatic depth as it cooks into the broth.
The step that matters
Keep the simmer gentle. A hard boil makes the liquid cloudy and emulsifies fat into it, while a gentle simmer keeps the broth clearer and cleaner-tasting.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, meat, celery, onion):
- Garlicfits better
- Thymefits better
- Cuminfits about as well
- Parsleythe original
Fit is the average pairing score against chicken, meat, celery, onion. Candidates are from the same food group and used in at least 100 recipes.
