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

What each ingredient does

Egg whites
Whipped to a light foam, they give the icing lightness and help it set smoothly.
Powdered sugar
Adds sweetness and bulk, stiffening the icing as it is mixed in.
Grated chocolate
Provides the chocolate flavour and some body to the icing.

The step that matters

Gradually mix in the powdered sugar. Adding the sugar slowly lets it dissolve and blend evenly, avoiding lumps and an uneven, grainy texture in the finished icing.
