Place long strips of peel, sugar, mint and water into Thermo bowl and cook 10 min/100°C/speed 2. Allow to cool completely.
Add citrus juice and yeast and mix 10 sec/speed 2. Strain into sterilised glass jars removing all peel and mint. Close jars and leave out of the fridge for around 2 days until bubbles start to appear. You will know when you open the jar if it is ready to chill as there will be a definite release of fizz!
Serve over lots of ice with additional mint leaves and sliced strawberries/blueberries, lemons/limes etc.
