Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken and enrich the custard, while whipped whites add lightness and airy texture.
- Gelatine
- Sets the liquid mixture into a firm, sliceable structure as it cools.
- Milk
- Forms the liquid base that the eggs thicken and the gelatine sets.
- Sugar
- Adds sweetness and helps balance the richness of the eggs and milk.
The step that matters
Fold the egg whites after removing the mixture from heat. If the base is still very hot, the whites can cook and lose volume, and the mixture can deflate. Folding gently off the heat keeps the foam intact so the set dessert stays light.
