A word about Kefir. I can't imagine drinking this plain, yuk, but when put into a shake...YUM! I made it in an attempt to use it to can fermented vegetables...ok, that didn't sound right, just think "sauerkraut". Well, THAT was disgusting. So I had used the better part a $7 gallon of raw milk to make this stuff and now I have a half gallon of this stuff that looks REALLy disgusting in the glass jar. But wait! I mistakenly think this is Kefir, but it is really whey. Oops! So now I'm really stuck, right? I shake the jar and it looks like milk with floating curds, but smells ok. It's supposed to last 6 weeks in the fridge. So what do I do? Make a shake! Well, needless to say, it will not go to waste. It was delicious! But like I said, I thought it was kefir...I will drink until finished and THEN make some Kefir. I think it will taste about the same and actually be a bit creamier, and of course, good for me!
