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 ↓

Butter and flour 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 dish, mashed into a smooth, soft texture.
- Butter
- Adds richness and a smoother, silkier mouthfeel to the mashed turnips.
- Flour
- Thickens the mashed turnips slightly, giving them a firmer body.
The step that matters
Drain the turnips thoroughly. Excess water left after boiling dilutes the flavour and loosens the mash, so it turns watery rather than smooth. Draining well keeps the texture thick and concentrated before the butter and flour are added.
Swap the turnip
How well each one fits the dish's main ingredients (butter, flour, pepper):
- Shallotfits better
- Chivefits about as well
- Capsicumfits about as well
- Turnipthe original
Fit is the average pairing score against butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
