Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Turnips with White Sauce
Ingredients
Directions
Prepare the turnips
Peel the turnips, cut them into strips, then dice.
Cook
Cover the turnips with hot water and cook until tender, about 1 hour.
Drain the turnips and pour the boiled milk over them, then return to the heat.
Thicken and serve
Rub the butter and flour together, then stir into the turnips until the milk thickens.
Add salt and pepper to taste, and serve.

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 into a tender vegetable base.
- Sweet milk
- Forms the creamy liquid that the sauce is built from.
- Butter
- Adds richness and fat to the sauce, smoothing its flavour and mouthfeel.
- Flour
- Thickens the milk into a white sauce as it heats and coats the turnips.
The step that matters
Stirring the butter and flour into the milk. Flour needs to be fully rubbed into the butter and then stirred into hot liquid so it disperses evenly. If added in lumps it will not hydrate smoothly, leaving floury clumps instead of a silky sauce that thickens as the starch swells with heat.
Swap the turnip
How well each one fits the dish's main ingredients (milk, butter, flour, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Turnipthe original
Fit is the average pairing score against milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
