Equipment

  • 1 Fermenting Jar or Fermenting Kit See notes for alternatives

Ingredients
  

  • 2 cups Blueberries
  • 6 Tbsp Kombucha, unflavoured
  • ¾ tsp Salt
  • 6 Tbsp Sugar
  • 9 Tbsp Water

Instructions
 

  • Mix all ingredients except for the blueberries.
  • Clean blueberries and then put them in the fermentation jar.
  • Pour the kombucha-sugar mixture on top.
  • Put the fermentation weight on top of the blueberries.
  • After twenty-four hours, taste-test daily until desired doneness. For us, we determined this was after three days, but the length of time will vary based on the temperature in your kitchen and various other factors.
    Transfer to a clean jar and store in the fridge.
    I'm not sure of the shelf life, but the jar in our fridge has been there a month and they're still good.

Notes

A fermentation kit usually has a jar, a weight, and an airlock. This is the one I have and it worked perfectly for this. (I can't find it on Amazon, but if you're in Canada, I got it at Canadian Tire. Alternatively, here's a more expensive and more complete kit from the same company available on Amazon, though it looks like it's several lids and weights but you provide your own jar.) If you don't have a fermentation kit, you can use any jar that's big enough to hold all of this, and then use a Ziplock bag filled with water as a weight. You might get scum forming on the bag and that's okay.
