Passover Confectioners’ Sugar


In a blender or food processor, whirl 1 cup minus ½ tablespoon regular granulated sugar until it is powdery. Place in a small bowl and stir in ½ teaspoon potato starch. Sift before using. (Recently commercial Passover confectioners’ sugar, made without cornstarch, has appeared in some stores with large kosher-for-Passover sections. If available, by all means use it here.)
