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

What each ingredient does

Egg whites
Whipped with sugar to form a smooth, stable icing that holds the banana layer.
Powdered sugar
Sweetens the icing and dissolves smoothly into the whipped egg whites.
Bananas
Provide the fruit flavor and moisture for the filling layer.

The step that matters

Beat the egg whites and gradually add the powdered sugar until smooth. Adding sugar slowly lets it dissolve fully into the egg whites, giving a smooth, stable icing; adding it all at once can leave grainy or loose texture.
