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):

  1. Garlicfits better
  2. Thymefits better
  3. Cuminfits about as well
  4. 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.
