Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Chicken Broth
Ingredients
Directions
Place the fowl joints in a well-closed saucepan.
Add the beef or veal bone, onion, carrot, parsley, salt, and enough water to cover.
Bring to a boil, then skim off any foam.
Reduce heat and simmer gently until the broth is flavorful.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main chicken flavour and body of the broth as it simmers.
- Beef or veal bone
- Adds savoury depth and body to the broth during long simmering.
- Onion
- Adds sweetness and aromatic flavour to the broth.
- Carrot
- Adds subtle sweetness and aroma to the broth.
The step that matters
Skim off the foam after boiling. Foam carries proteins and impurities that cloud the broth and can taint its flavour. Removing it early keeps the broth clearer and cleaner tasting.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, parsley):
- Parsnipfits better
- Turnipfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against beef, carrot, parsley. Candidates are from the same food group and used in at least 100 recipes.
