Ingredients

Directions

Prepare the carrots

Scrape, wash, and scald the carrots, then cut them into slices.
Boil the slices in hot water with a lump of butter until cooked, then drain.

Add white stock, egg yolks, and lemon juice, stirring until combined.

Finish and serve

Toss the carrots in the sauce without boiling, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour: Thickens the butter and stock into a smooth, cohesive sauce.
Egg yolks: Enrich the sauce, adding body and a creamy texture as they set gently.
Butter: Adds richness and fat, carrying flavour and giving the sauce a smooth mouthfeel.
Lemon juice: Adds acidity that brightens the sauce and balances the richness of the yolks and butter.

The step that matters

Toss the carrots in the sauce without boiling. Egg yolks thicken when heated but curdle or scramble if they get too hot. Keeping the sauce below boiling keeps it smooth and creamy.
