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

What each ingredient does

Gelatine
Sets the liquid custard into a firm, sliceable jelly as it chills.
Egg yolks
Thicken the milk into a custard and add richness and colour.
Egg whites
Are folded in to lighten the mixture and add airy texture.
Milk
Forms the base of the custard and contributes creaminess.
Sugar
Sweetens the custard and balances the egg flavour.

The step that matters

Cooking the custard. Egg yolks thicken as they heat, but overheating can curdle them into grainy bits. Cook gently over the double boiler, stirring, until the custard coats a spoon, so it stays smooth before the gelatine and egg whites are added.
