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

What each ingredient does

Egg whites
Beaten to a stiff foam that gives the icing lightness and body.
Powdered sugar
Sweetens the icing and stiffens the whipped whites into a spreadable coating.
Chopped almonds
Add crunch and nutty flavor to the icing.
Flour
Provides the structure that holds the shaped dough together through baking.

The step that matters

Adding the powdered sugar. Sugar should be added gradually to stiff egg whites. Adding it too fast deflates the foam, so the icing loses its volume and will not spread or dry as intended.
