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 thickens into a soft custard.
- Egg white
- Whipped foam adds lightness and sets gently when scalded in the hot milk.
- Egg yolk
- Its proteins set on heating, thickening the milk and adding richness.
- Sugar
- Adds sweetness and balances the richness of the yolk.
The step that matters
Let the mixture boil briefly. Egg yolk proteins thicken the milk as they heat, but overheating can make them curdle or scramble. Boiling only briefly keeps the custard smooth.
