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
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the broth
In a pot, combine onion, carrot, celery, bay leaf, peppercorns, and meat.
Add water and bring to a boil.
Reduce heat and simmer for 1.5 hours.
Strain the broth and return to the pot.
Season and serve
Add vinegar, Worcestershire sauce, and salt.
Slowly stir in the beaten egg and parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef or veal
- Provides the meaty flavour and body of the broth as it simmers.
- Egg
- Stirred in beaten, it sets into fine strands that add body to the soup.
- Vinegar
- Adds a sharp acidity that brightens the rich, savoury broth.
- Worcestershire sauce
- Adds savoury depth and a tangy, fermented note to the broth.
The step that matters
Slowly stir in the beaten egg. Pouring the egg in slowly while the broth is hot and moving lets it disperse and set into fine strands. Dumping it in at once can leave clumps of cooked egg instead of a smooth, silky texture.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, beef, vinegar, sauce, egg, parsley):

- Onionthe original
Fit is the average pairing score against carrot, celery, beef, vinegar, sauce, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
