Why it works: Turnip and flour match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,874 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mashed Turnips
Ingredients
Directions
Prepare the turnips
Pare and boil the turnips until three-quarters done.
Squeeze them between two plates to remove excess water.
Finish the mash
Place them in a saucepan and add flour, fresh butter, cream, and coarse sea salt, a little of each.
Mix well over low heat and stew gently for 15 minutes.
To keep them white, avoid overcooking; add powdered sugar if desired.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the main body of the mash, with a mild, slightly sweet flavor when cooked.
- Flour
- Thickens the mash and helps it hold together as it stews.
- Fresh butter
- Adds richness and a smooth, silky mouthfeel.
- Cream
- Adds moisture and creaminess, softening the mash's texture.
The step that matters
Avoid overcooking the turnips. Overcooked turnips become darker and more bitter, and they release more water, which thins the mash and dulls its white color. Stopping at three-quarters done keeps the flesh firm enough to absorb the butter and cream during the gentle stew.
Swap the turnip
How well each one fits the dish's main ingredients (flour, butter, cream, sugar):
- Arrowrootfits better
- Leekfits better
- Sweet potatofits better
- Turnipthe original
Fit is the average pairing score against flour, butter, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
