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

What each ingredient does

Egg yolks
Thicken the custard as they set when whisked into the heated milk.
Egg whites
Whipped into foam, they lighten the sauce and give it an airy, fluffy texture.
Sugar
Sweetens the custard and helps stabilise the yolks while they cook.
Milk
Forms the liquid base of the custard that the yolks thicken.

The step that matters

Heating the custard. Egg yolks thicken as they heat but can scramble if the mixture gets too hot or is not whisked constantly. Stop once it coats a spoon so the custard stays smooth.
