Method
Pre-heat oven to 100⁰C. Line 2 baking trays with baking parchment.
Drain the tin of chickpeas, keeping the liquid (keep the chickpeas for a different use).
Put the chickpea water in a mixing bowl with the cream of tartar.
Whisk the chickpea water and cream of tartar with an electric whisk for a few minutes, starting on a low speed and gradually building up.
Add the sugar gradually (a tablespoon at a time), still gradually building up the speed, until you get firm glossy peaks. This can take well over 10 minutes, so please be patient.
Add the vanilla essence extract and whisk well.
Using a piping bag or just using a spoon, make small circles out of mixture onto the baking tray, about 3cm wide.
Bake in the preheated oven for 90 minutes, or until the circles are firm and can easily be taken off the baking parchment.
Allow the meringues to cool fully before using.
Store in an airtight container for up to 3 weeks.
