Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the milk and chocolate mixture into a smooth, sliceable custard as it heats.
- Egg yolks
- Enrich the filling and help it set into a rich, creamy texture.
- Egg whites
- Whipped with sugar to form the light, stable meringue topping.
- Grated chocolate
- Provides the chocolate flavour and deep colour of the filling.
- Milk
- Forms the liquid base of the custard, giving body and creaminess.
The step that matters
Adding the cornstarch mixture to the boiling milk. Cornstarch only thickens fully when the mixture reaches a boil, and it can clump if added undissolved. Dissolving it in cold milk first and stirring it in while the mixture is hot keeps the filling smooth and properly thickened.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
