Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
To Mash Turnips
Ingredients
Directions
Cook the turnips
Split large turnips and boil them until very tender.
Press out the water thoroughly using a colander or a coarse sieve.
Place the turnips in a clean saucepan and stir constantly over gentle heat until dry.
Finish and serve
Add salt, butter, and cream or milk, and stir for 5 to 6 minutes until absorbed.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Provide the bulk and mild, slightly sweet flavour of the mash once their water is removed.
- Butter
- Adds fat and richness, giving the mash a smooth, silky mouthfeel.
- Cream or milk
- Adds moisture and creaminess so the mash becomes smooth rather than dry and grainy.
The step that matters
Drying the turnips before adding liquid. Turnips hold a lot of water. If it is not pressed out and the mash is not stirred over gentle heat until dry, the added cream or milk will make the mash thin and watery.
Swap the white pepper
The recipe marks white pepper as optional. How well each one fits the dish's main ingredients (turnip, butter, cream):
- Capersfits better
- Nutmegfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against turnip, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
