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

What each ingredient does

Milk
Forms the liquid base that the egg yolks thicken into a smooth sauce.
Egg yolks
Thicken the warm milk into a custard-like sauce as they set gently with heat.
Egg whites
Fold in to lighten the sauce and add a airy, delicate texture.
Vanilla
Adds the characteristic aroma and flavour of the sauce.

The step that matters

Stir in the egg yolks until the mixture thickens like boiled custard. Egg yolks set when heated, but if the milk is too hot or heated too fast, the yolks can scramble into lumps. Stirring constantly and keeping the heat gentle lets the proteins thicken the sauce smoothly.
