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 the vegetables
Wash and dry the vegetables, then cut them into thin shreds, about 1 inch long.
Make the soup
In a stew‑pan, melt the butter over low heat and add the vegetable shreds and a small pinch of sugar. Stir until slightly browned.
Pour in the clear stock and simmer gently for 1 hour, or until the vegetables are tender.
Remove any scum and fat from the surface.
Half an hour before the soup is done, add 2 lumps of sugar, 2 pinches of salt, 2 pinches of pepper, the cabbage lettuces, and the parsley leaves (previously immersed in boiling water for 1 minute).
Boil for an additional 30 minutes, skim carefully, and serve with diced fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Adds sweetness, colour and body to the soup as they soften in the stock.
- Turnips
- Contribute a mild sweetness and soft texture as they cook in the stock.
- Butter
- Carries the vegetables' flavour and helps them brown lightly at the start.
- Clear stock
- Forms the liquid base that carries the flavour of the vegetables.
- Cabbage lettuces
- Add leafy body and a fresh, green flavour near the end of cooking.
- Onions
- Add savoury depth and aroma as they soften and sweeten in the stock.
The step that matters
Simmering the vegetables gently. A gentle simmer lets the shreds soften evenly and keeps the stock clear. A hard boil breaks up the vegetables and makes the soup cloudy.
Swap the leek
The recipe marks leek as optional. How well each one fits the dish's main ingredients (carrot, turnip, celery, onion, butter, sugar, pepper):
- Leekthe original
- Parsnipfits about as well
- Okrafits less well
- Mustardfits less well
Fit is the average pairing score against carrot, turnip, celery, onion, butter, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
