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 light, airy structure.
Powdered sugar
Sweetens the frosting and thickens it as it is beaten into the whites.

The step that matters

Gradually add the powdered sugar while beating constantly. Adding sugar slowly lets it dissolve into the whites and stabilize the foam. Dumping it in at once can deflate the foam and leave a grainy, loose frosting.
