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

What each ingredient does

Egg
Thickens the chocolate mixture as it heats and adds richness to the filling.
Milk
Provides the liquid base that the chocolate and egg blend into.
Baker’s chocolate
Provides the chocolate flavor and body of the filling.
Sugar
Sweetens the chocolate filling and balances its bitterness.

The step that matters

Stir continuously over heat until the mixture thickens. Egg proteins set when heated, but if the mixture gets too hot or is left unstirred, the egg can scramble into lumps. Constant stirring spreads the heat evenly so the filling thickens smoothly.
