2 cups granulated sugar
3/4 cup water
2 tablespoons unflavored gelatin
1/2 cup cold water
1 teaspoon vanilla extract
1/2 teaspoon salt
Mix granulated sugar with the 3/4 cup water. Simmer to soft-ball stage. Remove from heat. Soften gelatin in the 1/2 cup cold water. Place on a large platter. Pour hot syrup over softened gelatin. Stir until dissolved. Let stand until partially cooled.
Whip until thick and white, and mixture will nearly hold its shape. Add vanilla extract and salt. Pour into straight-sided pans lined with equal parts of cornstarch and confectioners' sugar, mixed together. Let stand in cool place until firm (not in refrigerator). Cut into squares with scissors and dust with confectioners' sugar.
