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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal stock
- Provides the liquid base and the savoury, meaty flavour of the soup.
- Carrots
- Add natural sweetness, colour, and a tender bite as they cook.
- Spring turnips
- Add mild sweetness and a tender texture to the broth.
- Spring leeks
- Add a mild onion-like aroma and sweetness as they soften.
- Green peas
- Add sweetness, bright green colour, and a soft texture.
The step that matters
Keep the stock hot but do not boil it. Vigorous boiling makes stock cloudy and can break down its delicate flavour and fat, while gentle heat keeps it clear. Holding it just below the boil also keeps the vegetables tender rather than overcooked.
Swap the peas
How well each one fits the dish's main ingredients (veal, carrot, turnip, leek):

- Chestnutfits about as well
- Peasthe original
Fit is the average pairing score against veal, carrot, turnip, leek. Candidates are from the same food group and used in at least 100 recipes.
