Lacto-Fermented Watermelon Soda

4 cups watermelon cut into chunks 1/2 cup cane sugar organic, dehydrated cane juice or rapadura 1/4 cup whey, ginger bug or water kefir or 1/8 tsp champagne yeast 1 quart water filtered

* Boil sugar in water for a few minutes and stir to dissolve. Cool to room temperature. * Cut watermelon into chunks and puree in blender or food processor. * Strain out in a strainer covered with cheesecloth to get the watermelon juice. * Add the juice and the whey to the sugar water in a 2 quart glass ball jar or demijohn * Let it ferment on your counter for at least 2 days and up to 10 days. The longer you let it ferment the less sugar there will be as the bacteria will consume and convert the sugar during fermentation. Swish the soda around once a day to prevent mold from forming on the surface. * Transfer to soda bottles. Soda bottles increase the natural carbonation. The carbonation will increase rapidly. Be sure to release the pressure that builds every day until you’re ready to transfer them to the fridge. Do this over the sink or outside as the geyser effect is common.
