Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Prepare the vegetables
Peel the button onions and leave them whole.
Scrape and clean the carrots, then pare off the outer red part and cut the parings into pea-sized bits. Do the same with the turnips.
Stew the carrots in water for 10-15 minutes until tender.
Make the macédoine
In a pan, fry the onions and turnips in butter with the sugar until glazed but not burned.
Add the stewed carrots and toss all the vegetables together.
Stir in the Bechamel sauce and season with salt and pepper.
Cook until the sauce thickens and reduces.
Finish and serve
Beat the egg yolk with the cream and stir it in just before serving, ensuring the heat is off to prevent curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the vegetables and helps them brown lightly while glazing.
- Bechamel sauce
- Provides a creamy base that coats the vegetables and thickens as it reduces.
- Egg yolk
- Adds richness and thickens the sauce gently when heated without boiling.
- Cream
- Adds richness and smoothness, softening the sauce's texture.
- Sugar
- Caramelizes on the onions and turnips, adding sweetness and golden colour.
The step that matters
Adding the egg yolk and cream. Egg yolk proteins coagulate and curdle when overheated, so the mixture must be stirred in off the heat. Gentle warming thickens it smoothly instead of producing grainy lumps.
