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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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; mashing them until smooth gives the purée its texture.
- Butter
- Adds richness and a smooth, silky mouthfeel to the mash.
- Cream
- Adds moisture and richness, loosening the mash into a creamy texture.
- Flour
- Thickens the mixture so it holds its body when heated.
The step that matters
Press out all the water. Turnips hold a lot of water; if it is not pressed out, the mash turns thin and watery, and the added cream and flour cannot thicken it properly.
Swap the turnip
How well each one fits the dish's main ingredients (butter, cream, flour):
- Leekfits better
- Arrowrootfits better
- Chivefits better
- Turnipthe original
Fit is the average pairing score against butter, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
