Why it works: Onion and turnip match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 7,585 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while the flour is cooked into a roux.
- Flour
- Thickens the liquid into a smooth sauce as it cooks with the butter and water.
- Turnips
- Form the main body of the dish and become tender as they simmer in the sauce.
- Egg yolk
- Enriches and thickens the sauce to a creamy texture when stirred in at the end.
- Cream
- Adds richness and a smooth, silky texture to the finished sauce.
The step that matters
Stirring in the egg yolk and cream. Egg yolk thickens when heated gently but can scramble if the sauce is boiling. Stir it in off the heat or over low heat so the sauce stays smooth and creamy.
