The milk kefir is voracious! I've had good results using it in smoothies, and as a replacement for yoghurt in a curry and in place of buttermilk in pancakes...any ideas will be much appreciated :)
I drank a lot of kombucha last summer, and kept finding I didn't have jars to ferment anything else....so production is ramping up this year.
Caspian sea yoghurt sounds enchanting, I'm off to look it up.
