½ cup unflavored kombucha, this should be unpasteurized, unflavored store-bought kombucha
Instructions:
Make tea: bring 3½ cups water to a boil in a clean pot. remove from heat and add 2 bags black tea. allow tea to steep for about 15 minutes. remove tea and stir in ¼ cup white sugar. let tea cool to room temperature.
Alternatively, boil only 1 cup of water and add the remaining 2½ cups of cold water once the tea has steeped and sugar has been added. this will quicken the process.
Add starter: add ½ cup unflavored kombucha then pour everything into a large glass jar.
Ferment: cover with a clean cloth and secure with a rubber band. set somewhere dark and room temperature (70-75°f, 21-24°c) for 1 to 4 weeks, until a ¼ inch (½ cm) scoby has formed.
