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

What each ingredient does

Egg whites
Whipped into foam that gives the icing its light, airy structure.
Sugar
Sweetens the icing and, dissolved into the boiled syrup, helps stabilize the foam.
Cream of tartar
Acidifies the mixture, helping egg white foam stay stable and resist collapsing.

The step that matters

Pouring the boiled syrup and whipping immediately. The syrup must be hot when it meets the egg whites so it cooks and stabilizes the foam. Delaying the whipping lets the foam deflate and the icing lose volume.
