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

What each ingredient does

Egg whites
Whipped into a foam that gives the frosting its airy structure and body.
Powdered sugar
Sweetens the frosting and dissolves into the foam, helping it set stiff.
Grated chocolate
Adds chocolate flavor and cocoa fat, giving richness to the frosting.

The step that matters

Adding the powdered sugar gradually. Adding sugar slowly while beating lets it dissolve evenly into the egg white foam. Dumping it in at once can deflate the foam and leave the frosting grainy and loose.
