Why it works: Turnip and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 5,252 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
- Turnips
- Form the body of the soup, becoming soft and tender as they stew and simmer.
- Butter
- Adds fat and richness, and gently cooks the turnips without browning them.
The step that matters
Stewing the turnips without browning. Over low heat the butter should only warm and soften the turnip slices. If the heat is too high, the milk solids and sugars in the butter and turnips brown, changing the flavour and colour of the soup.
Swap the turnip
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Turnipthe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
