In a medium saucepan, combine sugar, corn syrup, salt and ½ cup of hot water. Bring to boil over a medium high heat. Cook, without stirring, for 9 minutes

Remove from heat and add the thickened gelatin and stir to combine. Allow to cool for 5 minutes.

Meanwhile, beat your egg whites, and vanilla (with whisk attachment) on high until stiff peaks form. Reduce the mixer speed to slow, and slowly pour in the sugar syrup in a steady but slow stream. Once all incorporated, turn your mixer on medium high and beat until it has doubled in volume.
