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 ↓

Make the sauce
In a stewpan, combine the vegetables, ham, and butter; fry until softened but not browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the stock into a smooth, body-rich sauce as it cooks.
- Vinegar
- Adds acidity that sharpens the flavour and is reduced by boiling.
- Ham
- Contributes savoury, salty flavour to the base as it fries with the vegetables.
- Carrots
- Add sweetness and body to the sauce as they soften during frying and simmering.
- Onions
- Build savoury sweetness and depth as they soften and brown lightly in butter.
The step that matters
Fry the vegetables until softened but not browned. Gentle frying softens the vegetables and releases their sugars and flavour. If they brown too far, the sauce can turn bitter and dark, so the colour and flavour of the finished sauce depend on keeping them pale.
Swap the clove
How well each one fits the dish's main ingredients (celery, carrot, onion, shallot, garlic, turnip, leek):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against celery, carrot, onion, shallot, garlic, turnip, leek. Candidates are from the same food group and used in at least 100 recipes.
