From now on, JJ and I are drinking Kefir every day. It' s not only
healthy, it's also very tasty and cheap. We got some water kefir grains
from Pushpa and now we're trying to keep them alive.
It isn't that difficult, you just need sugar, lemon and some dried fruit.

want some kefir grains; in a week mine will be doubled, so I can share
