In a bowl add the kombucha and gelatin, mix and set aside to allow the gelatin to 'bloom'.
Add your fruit, lemon juice and any of your optional extras to a food processor and blend until smooth.
Thermomix Option- Add the blended fruit and kombucha gelatin mix to the thermomix and set for 5 mins, speed 3, 50 degrees.
Stove Option- Add the blended fruit and kombucha gelatin mix to a small saucepan and heat over the lowest heat until all the gelatin has dissolved, stirring constantly.
Remove from heat and set aside to cool to room temperature. Once at room temperature pour into moulds or into a baking paper lined container to set in the fridge for at least 4 hours.
Once set you can slice if it's in a tray or remove from moulds. These can be stored in the fridge for up to a week or in the freezer for a few months.
