Bright white icing that dries quickly. Commonly used to "glue" gingerbread houses together.
Ingredients
4 tbsp aquafaba
2 cups icing (confectioner’s) sugar
Preparation
In a stand mixer (or using a hand blender or beater), froth the aquafaba on high-speed.
Add the icing sugar, a tbsp at a time, and continue to mix for about 10 minutes, until the sugar is incorporated and the mixture is thick and glossy. If you need to make it thicker, add more sugar.
If colouring, separate into bowls, and stir-in colours.
Transfer to a piping bag and use immediately.
Let stand for 2 hours to completely harden.
Makes enough for about 3 dozen cookies, if used sparingly. 2 dozen, if coating completely.
Can be stored in an airtight container in the fridge for up to 4 weeks (need to whip the mixture again, to loosen it up).
