Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated chocolate
- Provides the chocolate flavor and body of the filling.
- Egg yolks
- Thicken the custard and add richness as they set with heat.
- Cornstarch
- Thickens the filling by swelling in hot liquid as it boils.
- Sugar
- Sweetens the filling and stabilizes the beaten egg whites in the meringue.
The step that matters
Boil the chocolate mixture until thick. Cornstarch only thickens fully when the mixture reaches a boil, and the starch must be fully cooked to avoid a thin or grainy filling. Stirring prevents scorching on the bottom of the pan.
