Maple Sugar Frosting
Ingredients
Directions
Make the syrup
Break the maple sugar into small pieces and place in a saucepan with boiling water.
Stir occasionally until the sugar is dissolved.
Boil without stirring until the syrup can thread when dropped from the tip of a spoon.
Make the frosting
Gradually pour the syrup onto the beaten egg whites while beating constantly.
Continue beating until the mixture reaches the right consistency to spread.

What each ingredient does
- Maple sugar
- Provides the sweetness and maple flavor that defines the frosting.
- Egg whites
- Whipped to foam, they give the frosting its light, airy structure.
- Boiling water
- Dissolves the sugar so it can be cooked into a syrup.
The step that matters
Gradually pour the syrup onto the beaten egg whites while beating constantly. Hot syrup poured in too fast or without constant beating can cook and clump the egg whites, or deflate the foam. Steady beating lets the hot syrup cook the whites gently into a smooth, stable meringue-like frosting.
