Last year before I started making Kombucha I started experimenting with fermented soft drinks. I loved making them but the recipes I used I found overly sweet as they called for about 10 cups of sugar! After some experimenting I mastered the recipe for Fermented Watermelon soda you can Lacto-ferment it if you want but I prefer using my Kombucha to get it started you could use cider vinegar or something else with the MOTHER.
I used a 5litre food grade bucket to make my batch as I make very large amounts at once but you could use a fermenting jar or whatever you have handy. I have given the recipe for the smaller quantity below.
The flavor of this yummy and healthy soda is sour and sweet at the same time and a beautiful pink colour that your kids will go mad for!
Fermented Watermelon Soda
4 Cups Watermelon pureed
1/2 Cup Sugar
1/4 C Kombucha , Keffir, Whey, Apple cider vinegar,or ginger bug
1 Litre of warm water
- Place sugar and water in your vessel and stir to dissolve
- Add pureed watermelon
- Add the Kombucha (or starter of choice) and stir
- Cover with a cheesecloth and let it sit on the counter for 2 to 10 days I did 4 days as it is hot and summer here in Australia but it will depend of your climate and taste buds. 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.
- Strain the puree out and bottle leaving some head space for a second ferment to increase carbonation for a few days to a week and then pop in the fridge.
Enjoy Ice cold 🙂
