Place 100ml of water and Maple Syrup/Honey in a saucepan and bring to the boil over a medium heat.
At the same time sprinkle the gelatin over 100ml of water and allow to thicken.
Once the mixture is boiling reduce the heat slightly and add the thickened gelatin mixture, whisking vigorously to incorporated the gelatin and ensure no lumps remain.
Return to medium heat and return to the boil and boil for 1 minute, continuing to whisk.
Place the egg white in a clean bowl of a kitchen stand mixer with a whisk attachment.
Place mixture on medium and whisk until the egg white is frothy.
Pour the hot mixture in to the bowl, pouring slowly along the edge of the bowl.
Turn whisk to high and whisk for 5-7 minutes.
Add the Vanilla and whisk on high until firm but not set (another minute)
The mixture should be shiny and thick, but still able to be piped and spread.
Spread into a greased and lined dish or pipe out onto a greased and lined tray.
Allow to sit at room temperature overnight.
Once set sprinkle the arrowroot over Marshmallow pieces (this makes them less sticky and easier to handle). Alternatively, roll the pieces in arrowroot or you could even use desiccated coconut.
