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

What each ingredient does

Oranges
Provide the bulk of the filling and its bright citrus aroma and flavour.
Lemon
Adds acidity that brightens the sweetness of the filling.
Sugar
Sweetens the filling and helps give it a thick, spreadable body.
Egg white
Binds the chopped fruit and sugar together so the filling holds between cake layers.
