Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into stiff foam that gives the frosting its light, airy structure.
- Powdered sugar
- Sweetens the frosting and dissolves easily into the whipped whites.
- Grated sweet chocolate
- Adds chocolate flavour and sweetness to the frosting.
The step that matters
Gently stir in the powdered sugar and grated chocolate. Folding rather than vigorous stirring keeps the air bubbles in the whipped egg whites, so the frosting stays light and does not deflate.
