Yes - I found this gem too! Only I don't think I will be able to get ANYONE to try this one! That's OK - I LOVE it! Kefir is a fermented milk drink that originated in Turkey, Russia & surrounding areas. It is prepared by inoculating milk with kefir grains. Kefir grains are a combination of bacteria & yeast resembling cauliflower. I simply take one cup of milk & add the kefir, let it sit for a while (usually two days) & soon a yogurt like liquid is formed - I strain out the precious granules for a new batch & keep the thick liquid in the fridge. The kefir liquid then goes into the blender, along with some ice, a banana (or berries), flax seed, oats & sweetener (honey or vanilla). This "smoothie" is delicious, filling & healthy!
