Why it works: Leek and turnip 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
- Scotch barley
- Swells as it simmers, thickening the broth and giving it body and a chewy texture.
- Leeks
- Soften in the broth and add a mild, sweet onion-like flavour.
- Mutton chops
- Release flavour and gelatin into the broth as they stew until tender.
- Turnips
- Hold their shape in the broth while adding mild sweetness and earthy flavour.
- Carrots
- Add natural sweetness and colour while staying firm enough to hold their shape.
The step that matters
Skim off any fat. Mutton fat rises and can make the broth greasy and cloudy. Removing it while the broth is hot leaves a cleaner, lighter flavour.
Swap the carrot
How well each one fits the dish's main ingredients (mutton, leek, barley, turnip):
- Parsnipfits better
- Shallotfits about as well
- Asparagusfits about as well
- Carrotthe original
Fit is the average pairing score against mutton, leek, barley, turnip. Candidates are from the same food group and used in at least 100 recipes.
