Whilst we were out of PNG, we hid my Kombucha SCOBY (which my sister-in-law originally sent me from the US - dried) in the back of a dark cupboard, and I was relived to discover it survived. Whilst in Hagen some friends offered us blueberry & cinnamon Kombucha, which was delicious. I found frozen blueberries in the chiller, in one of the stores in Hagen (a rare and valuable find!), so I thought I’d try it. The result is a resounding success and will be repeated often, so long as I have blueberries in my freezer!
