- Whip the Marshmallow Mixture:
- Set your mixer on low with the bloomed gelatin ready then slowly stream the piping hot sugar syrup into the bowl careful not to splash as it will be extremely hot increase speed to high and whip for twelve minutes until it turns thick shiny and billowy it should form soft peaks and the outside of the bowl will cool noticeably
