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 ↓

Ingredients
Directions
Make the stock
Place the bones in a stock pot and cover with water.
Boil for at least 6 hours, adding hot water as needed.
Season and finish
About 1 hour before serving, add carrots, celery, herbs, parsley, onions, mace, cloves, peppercorns, and salt.

Beat the eggs with cold water and stir into the soup.
Simmer for 30 minutes, then strain again and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones
- Release gelatin and flavour into the water during long boiling, giving the soup body.
- Eggs
- Coagulate as they heat, gathering fine particles so the soup can be strained clear.
- Carrots
- Add natural sweetness and aromatic flavour to the broth.
- Onions
- Contribute savoury depth and sweetness as they cook slowly in the broth.
The step that matters
Stirring in the egg mixture. Eggs must be stirred in gently and simmered, not boiled hard. Proteins set as they heat and trap particles, which the final straining then removes; rough boiling breaks up the curds and leaves the soup cloudy.
Swap the mace
How well each one fits the dish's main ingredients (carrot, celery, parsley, onion, clove, egg):
- Thymefits better
- Marjoramfits better
- Dillfits better
- Macethe original
Fit is the average pairing score against carrot, celery, parsley, onion, clove, egg. Candidates are from the same food group and used in at least 100 recipes.
