I've gone crazy with kefir. I don't know why but my last batch of coconut milk kefir I decided to add some pumpkin puree. It tasted kind of icky after a couple of days of fermenting, not sour enough. So I let it go a few more days... just tasted it this morning. It is SOUR! And it is bubbling like a witches brew *cackle*. So I just decanted it and put it in the fridge, I hope the jar doesn't explode.
I think I'll have to put some sweetener in this one because it is so powerfully puckerworthy.
I'd better go loosen the lid, I'm scared it'll blow up.
