Place watermelon in the freezer for 6 hours or overnight.
Once ready to make slushie, remove from freezer for approximately 10-15 minutes prior to soften.
Add half all the ingredients - watermelon, lime, basil and Remedy Kombucha Wild Berry - to a blender and blitz until an iced slushy consistency is created. Pour into glasses.
Repeat with remaining ingredients.
Serve immediately with 2 small watermelon pieces popped into the top of the slushies together with lime pieces and fresh basil.
