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 ↓

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 and soften gently when scalded and simmered in the sauce.
- Butter
- Adds richness and a rounded flavour to the sauce and helps it coat the turnips.
- Flour
- Mixed with butter and stock, its starch thickens the sauce so it clings to the turnips.
- Pale stock
- Provides the liquid that moistens the flour and butter into a smooth sauce.
- Egg yolks
- Thicken and enrich the sauce as they warm, giving it a smooth, velvety body.
- Sugar
- Adds a little sweetness that balances the savoury stock and butter.
The step that matters
Stirring in the egg yolks. Egg yolks thicken by gentle heat, but if the sauce gets too hot or boils after they go in, the proteins set and curdle. Warm it gently and stir constantly so the sauce stays smooth.
Swap the turnip
How well each one fits the dish's main ingredients (butter, flour, sugar, egg):
- Chivefits better
- Leekfits better
- Shallotfits better
- Turnipthe original
Fit is the average pairing score against butter, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
