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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round beef
- Releases meat flavor and savory depth into the stock as it simmers.
- Beef bones
- Add gelatin and body, giving the stock a richer mouthfeel.
- Onion
- Adds sweetness and aromatic depth as it cooks down in the liquid.
- Carrots
- Contribute natural sweetness and rounded flavor to the broth.
- Potatoes
- Add starch that gives the stock a slightly fuller body.
- Tomato
- Adds acidity and brightness that balances the rich meat flavors.
The step that matters
Boil the beef, bones, and vegetables over low heat. Keeping the liquid at a gentle simmer rather than a hard boil lets fat and impurities rise to be skimmed, and prevents them from emulsifying into the broth, which keeps the stock clear.
Swap the onion
How well each one fits the dish's main ingredients (beef, potato, carrot, tomato, parsley, pepper, sherry):
- Capsicumfits better

- Onionthe original
Fit is the average pairing score against beef, potato, carrot, tomato, parsley, pepper, sherry. Candidates are from the same food group and used in at least 100 recipes.
