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, they give the icing a light, airy texture.
Powdered sugar
Adds sweetness and body, thickening the icing as it dissolves.
Grated chocolate
Supplies the chocolate flavor and richness of the icing.

The step that matters

Make the chocolate mixture smooth and glossy before adding it. Hot water helps the chocolate and sugar melt into a smooth mixture. Any lumps left at this stage will not dissolve later, so they will remain in the finished icing.
