What each ingredient does
- Egg whites
- Whipped into foam, they give the icing its light body and structure.
- Powdered sugar
- Dissolves into the whites to add sweetness and body, making the icing smooth and glossy.
The step that matters
Gradually add the powdered sugar. Adding sugar all at once can collapse the foam and leave lumps. Adding it slowly lets the sugar dissolve evenly while the whites keep their air, so the icing stays smooth and holds its shape.
