Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Julienne Soup
Ingredients
Directions
Prepare
Cut the carrots, turnips, green onions, celery, leeks, parsley, spinach, and lettuce into small pieces.
Cook and strain
Add the vegetables and peas to the veal stock and stew until tender.
Pass the mixture through a fine cloth to strain.
If the soup is not clear, beat the white and shell of an egg, stir it in, and boil for 5 minutes before straining again.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal stock
- Forms the liquid base that carries the flavour of the whole soup.
- Fresh green peas
- Add sweetness and a soft texture once stewed until tender.
- Carrots
- Contribute natural sweetness and body as they soften in the stock.
- Leeks
- Add a mild onion-like aroma that deepens the stock's flavour.
The step that matters
Clearing the soup with egg white. Beaten egg white and shell are stirred in and boiled so the proteins coagulate and trap cloudy particles. Boiling gently and then straining again lets the cleared soup pass through the cloth cleanly.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, celery, leek, parsley, spinach, lettuce):
- Parsnipfits better
- Beetrootfits better
- Endivefits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, celery, leek, parsley, spinach, lettuce. Candidates are from the same food group and used in at least 100 recipes.
