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.
