Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Thicken the filling as they set with heat and add richness.
Cornstarch
Thickens the milk mixture into a smooth, sliceable filling as it heats.
Flour
Adds additional thickening so the custard holds its body.
Milk
Forms the liquid base of the custard that thickens during cooking.
Sugar
Sweetens the filling and balances the bitterness of the chocolate.
Chocolate
Provides the main chocolate flavor and the filling's dark color.

The step that matters

Cook the filling until thick, stirring constantly in the double boiler. Starch thickens only when heated through, so the filling must be cooked long enough to set. Constant stirring keeps the starch and egg from scorching or lumping, and gentle heat stops the eggs from curdling.
