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

What each ingredient does

Grated chocolate
Provides the main flavor and body of the filling as it melts into the mixture.
Egg
Thickens the filling as it heats and helps it set into a creamy texture.
Sugar
Sweetens the filling and helps balance the bitterness of the chocolate.
Butter
Adds richness and a smooth, glossy mouthfeel to the filling.

The step that matters

Stirring over medium heat. Egg proteins thicken the filling as it heats, but if the mixture gets too hot or is not stirred constantly, the egg can scramble and leave lumps. Keeping the heat moderate and stirring until smooth helps the custard-like texture develop evenly.

Swap the walnut

How well each one fits the dish's main ingredients (chocolate, sugar, milk, egg, butter, vanilla):
