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 ↓
Beef Soup
Ingredients
Directions
Make the broth
Cover the beef with cold water in a pot.
Boil slowly for 3 hours.
Add cold water to stop the boil.
Skim off the top three times.
Add the onion, potatoes, carrot, turnip, and parsley.
Boil for 1 more hour.
Remove the meat and strain the vegetables into another vessel.
Finish the soup
Beat the eggs in the soup tureen.
Stir in the soup gradually to avoid curdling.
Add the vegetables.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavour and gelatin into the broth as it simmers slowly.
- Eggs
- Beaten eggs thicken and enrich the soup when stirred in gently.
- Potatoes
- Starch softens during cooking and gives the soup body.
The step that matters
Stir in the soup gradually. Adding hot soup slowly to the beaten eggs gently raises their temperature. Pouring it in all at once can scramble the eggs and cause curdling.
Swap the onion
How well each one fits the dish's main ingredients (beef, potato, carrot, turnip, parsley, egg, pepper):
- Parsnipfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against beef, potato, carrot, turnip, parsley, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
