Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken and enrich the filling, adding richness and a smooth custard body.
- Corn starch
- Thickens the boiling water mixture into a set, sliceable filling.
- Chocolate
- Provides the main chocolate flavour and colour of the filling.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
- Egg whites
- Whipped into a stiff meringue that forms the topping and browns in the oven.
The step that matters
Stirring the mixture into the boiling water until thickened. Corn starch only thickens fully once it reaches a boil, so the filling must be stirred constantly while it thickens. Undercooked starch leaves the filling thin and runny.
