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
Clarify the stock
Combine the stock, beaten egg whites, and shredded beef in a pan.
Slowly bring to a boil.
Remove from heat and let stand for 10 minutes to clear.
Strain through a clean towel or jelly bag.
Prepare the vegetables
Cut the vegetables into fine strips, about 1 inch long.
Boil the carrots, turnips, leeks, onions, and celery in a little boiling stock until tender. Drain the vegetables.
Finish and serve
Add the drained vegetables to the soup along with the lettuce, tarragon, and chervil. Boil for 15 minutes.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Coagulate as they heat, trapping particles so the stock clears to a clear broth.
- Lean beef
- Adds meaty flavour to the stock and, with the whites, helps clarify it.
- Brown stock
- Forms the base of the soup, carrying all the flavour.
- Carrot
- Adds sweetness and colour as a julienne vegetable.
- Leek
- Adds a mild onion-like flavour to the soup.
The step that matters
Letting the stock stand and straining it clear. Egg whites must be heated slowly so they coagulate gently and trap cloudy particles. Boiling hard breaks up the raft, and straining through a clean cloth removes what remains, so the broth stays clear.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, lettuce, egg, turnip, leek, tarragon):
- Beetrootfits better
- Endivefits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against carrot, celery, lettuce, egg, turnip, leek, tarragon. Candidates are from the same food group and used in at least 100 recipes.
