What each ingredient does
- Maple sugar
- Provides the sweetness and maple flavor, and sets the icing's texture as it cooks and cools.
- Egg whites
- Trap air when beaten, forming a light foam that gives the icing its lightness and body.
The step that matters
Boil to the soft ball stage. The sugar's concentration sets the icing's final texture. Stopping too early leaves it runny and soft, while boiling too long makes it stiff and grainy. Pour the syrup slowly so it cooks the whites gently without deflating them.
