Passover Powdered Sugar
Because confectioners' sugar contains cornstarch, it is not kosher for Passover. This makes a fine substitute.
- 1 tablespoon potato starch
- 1 cup granulated sugar
In a food processor, combine potato starch and sugar. Process until mixture is very powdery and resembles confectioners' sugar, about 2 minutes. Allow to settle for about 1 minute before removing processor cover.
