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

What each ingredient does

Eggs
Provide structure and richness, setting the filling as it bakes.
Butter
Adds fat for a smooth, tender texture and rich mouthfeel.
Sugar
Sweetens the filling and helps creaming trap air for a lighter texture.
Chocolate
Supplies the main flavour and richness of the filling.

The step that matters

Beat the mixture for ten minutes. Extended beating incorporates air and dissolves sugar, giving a smoother, lighter filling. Beating too little leaves a grainy or dense texture.
