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 ↓
Julien Soup
Ingredients
Directions
Prepare the vegetables
Clean and cut the carrots, turnip, leek, and celery into shreds about 1 inch long.
Place the vegetables in a saucepan with salt, sugar, vinegar, and cold water; boil until tender, about 20 minutes, then drain.
Finish the soup
In a separate pot, boil the stock, add the vegetables, and cook uncovered for 30 minutes.
Stir in cayenne and sherry, then serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness, colour and body once softened in the stock.
- Turnip
- Adds a mildly sharp, earthy flavour and firm texture that holds its shape.
- Celery
- Contributes a fresh, aromatic savoury note and some crisp texture.
- Stock
- Forms the liquid base that carries the flavour of the whole soup.
The step that matters
Boil the vegetables until tender before draining. Cooking shreds fully softens the fibres so they feel tender in the soup; undercooked pieces stay tough and chewy, while the boiling water and vinegar help keep vegetable colour bright.
Swap the celery
How well each one fits the dish's main ingredients (carrot, turnip, leek, sugar, vinegar, sherry):
