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 ↓
Soup Stock, or Broth
Ingredients
Directions
Make the stock
Place the cracked bone and solid piece of meat in the bottom of a soup kettle. Add cold water and heat gradually over the fire.
Skim off any blood and albumen that rises as it boils.
Add the whole carrot, turnip, onion, salt, pepper, herbs, parsley, and celery.
Cook slowly for 2 hours to secure flavor; longer cooking will create a jellied consistency.
Strain and chill
Strain through a sieve or a folded towel in a colander into an earthen vessel.
When cold, remove the fat that rises to the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef neck or bone
- Releases collagen and gelatin during long simmering, giving the stock body and flavor.
- Veal knuckle
- Adds extra gelatin, helping the stock set to a jelly when cold.
- Onion
- Adds sweet, savory aromatic flavor to the broth as it simmers.
The step that matters
Cook slowly for 2 hours. Gentle simmering extracts flavor without clouding the stock. Longer cooking extracts more gelatin, so the stock sets into a firm jelly rather than staying liquid.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (beef, carrot, turnip, onion, clove, pepper, parsley):
- Thymefits about as well
- Marjoramfits about as well
- Celerythe original
- Winter savoryfits about as well
Fit is the average pairing score against beef, carrot, turnip, onion, clove, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
