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
- Provides the main flavor, gelatin and body that the stock is built on.
- Water
- Acts as the solvent that slowly extracts flavor and collagen from the bones and meat.
- Onion
- Adds savory depth and mild sweetness as it simmers into the liquid.
The step that matters
Simmer gently until half the water remains. Long, gentle simmering extracts collagen and flavor slowly; a hard boil makes the stock cloudy and greasy, while too little reduction leaves it thin and weak.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, onion):

Fit is the average pairing score against chicken, onion. Candidates are from the same food group and used in at least 100 recipes.
