About Powdered Sugar
Break up large lumps without packing the sugar. If a frosting recipe specifies a weight, weigh that amount and then sift it to avoid gritty pockets in the finished mixture.
Most commercial powdered sugar includes an anti-caking starch. It is not a direct volume substitute for granulated sugar, and adding more to thicken icing also increases sweetness.
Tips for measuring Powdered Sugar
- Read whether sifting comes before or after measuring.
- Add icing liquid gradually after the sugar is measured.
Common mistakes
- Compressing fluffy sifted sugar to reach an unsifted cup measurement.
