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

What each ingredient does

Cream
Provides the fat and body that make the frozen dessert rich and smooth.
Sugar
Sweetens the custard and softens its texture once frozen.
Egg yolks
Thicken the custard as they cook and add richness through their fat and emulsifiers.
Vanilla bean
Adds aroma and flavour from its seeds infused into the cream.

The step that matters

Cook until the mixture begins to thicken. Egg yolks thicken when gently heated, but overheating scrambles them into lumps. Cook slowly over simmering water and stop as soon as the custard coats a spoon.
