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 of the custard that soaks into the sponge cake.
- Egg white
- Whipped until stiff, it traps air and gives the dessert a light, airy texture.
- Egg yolk
- Its proteins set when heated, thickening the mixture and adding richness.
- Sugar
- Adds sweetness and helps balance the richness of the egg yolk.
- Sponge cake
- Absorbs the warm custard, adding moisture and a soft base.
The step that matters
Stir the beaten egg yolk with the sugar and let it boil briefly. Egg yolk proteins set when heated, which thickens the custard. Too much heat or too long at a boil can make the yolk curdle and turn grainy, so keep stirring and watch closely.
