First step is to source the milk kefir grains. I put an APB on our local Facebook group and in short order found 2 friends who had grains to share.
The grains grow over time allowing you to share with friends and family.
When you get the grains you need to feed them. They prefer organic raw whole milk but you can use whatever you have on hand. Put the grains in a glass jar and add milk. Start with a jelly jar of milk for about 1 TBSP grains. Cover with a coffee filter and the ring to prevent any fruit flies etc from getting in the jar.
