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 adds body to the filling.
Cornstarch
Thickens the filling as its starch swells and sets when heated in liquid.
Eggs
Add richness and help thicken the custard as they cook.
Sugar
Sweetens the filling and balances the bitterness of the chocolate.

The step that matters

Cooking the filling until thick. Cornstarch only thickens once the mixture is hot enough for its starch to swell, and the eggs set as they heat. Cooking gently while stirring prevents lumps and scorching, and the filling should be thick enough to coat a spoon.
