Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 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
- Lamb loin
- Provides the main meat, releasing flavour and richness into the broth as it simmers.
- Carrots
- Add sweetness and body to the broth as they soften during long simmering.
- Turnips
- Contribute mild sweetness and a tender texture after long cooking.
- Onion
- Builds savoury depth as its sugars and aromatics mellow in the simmering liquid.
- Peas
- Add sweetness, colour and a soft texture when cooked briefly at the end.
The step that matters
Add peas long enough before serving to cook them. Peas are small and cook quickly, so adding them too early turns them mushy and dull in colour. Adding them shortly before serving keeps them tender, bright and distinct in the soup.
Swap the peas
How well each one fits the dish's main ingredients (lamb, beef, carrot, turnip, onion, pepper):
