Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the custard as it cools, giving it a firm, sliceable body.
- Egg yolks
- Thicken and enrich the custard, adding richness and a smooth texture.
- Egg whites
- Beaten in to lighten the custard, adding a airy, fluffy texture.
- Milk
- Forms the liquid base of the custard, providing body and creaminess.
- Sugar
- Sweetens the custard and helps balance the richness of the egg and milk.
The step that matters
Pour the scalding milk over the egg mixture and stir. Adding hot milk too quickly or without stirring can scramble the egg yolks. Pouring slowly while stirring gently warms the yolks so the custard thickens smoothly.
