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

What each ingredient does

Sweet milk
Forms the liquid base that dissolves the sugar and chocolate into a smooth filling.
Sugar
Adds sweetness and helps thicken the filling as it cooks.
Sweet chocolate
Provides the chocolate flavor and body that sets the filling as it cools.
Lemon extract
Adds a bright aroma that balances the sweetness of the chocolate.

The step that matters

Boil the mixture until it thickens. Cooking the milk, sugar and chocolate to a boil lets the sugar dissolve fully and the mixture thicken enough to spread and hold between cake layers. Undercooked filling stays runny, while overcooking can make it grainy or stiff.

Swap the lemon
