Why it works: Turnip and mustard match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 290 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Turnips in White Sauce
Ingredients
Directions
Prepare the turnips
Peel and quarter the turnips.
Boil the turnips in salted water with a little butter until tender.
Drain the turnips and press them dry with the back of a large plate.
Rub the turnips through a colander into a clean saucepan.
Finish and serve
Add the butter, white pepper or cayenne, and salt if needed.
Stir over the heat until the butter is mixed and the turnips are hot.
Serve with white sauce poured over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the main bulk of the dish; their starch and fibre become a soft purée when rubbed through.
- Butter
- Adds richness and a smooth, silky mouthfeel to the mashed turnips.
- White sauce
- Adds moisture and a creamy, mild coating over the finished turnips.
The step that matters
Pressing the turnips dry. Excess water left in the boiled turnips dilutes the purée and makes it loose. Pressing them dry before rubbing through the colander keeps the texture thick and smooth.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (turnip, butter, sauce, white pepper, sugar):
- Leekfits about as well

- Mustardthe original
Fit is the average pairing score against turnip, butter, sauce, white pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
