Day 1: Dissolve ⅓ cup of the sugar in ⅔ cup (150 mL) of hot spring or filtered water. Once dissolved, add this and the remaining cold filtered or spring water to a large Mason jar. Add the strawberries and cardamom pods, and close the jar. Leave the jar at ambient room temperature (kitchen counter is fine).
Day 2: Give the jar a shake.
Day 3: Dissolve 3 tablespoons of sugar in a little hot water again and add to the contents of the Mason jar. Once cool, close securely and shake gently again.
Day 4: You should start seeing bubbles and/or foam forming on the edges and top of the liquid in the jar. If not, leave it one more day.
If the bubbles are there, take a 1-liter swing top bottle, and using a funnel, pour in the kombucha (or your previous soda) and strain the fermented fruit and pour the liquid into the bottle. Close the bottle and let it sit at room temperature for another day or so.
Some sodas may not need the 5th day at room temperature, so you can refrigerate immediately. You will know this from the amount of fizz you see once you pour it into the bottle.
Day 6: Refrigerate the bottle and open carefully when ready to drink!! Always refrigerate once opened. Time to get started on your next soda!
Remember to keep ½ cup or so for your next soda!
