Step 1: I take a clean glass quart jar and put a Tablespoon (or more) of Kefir grains into it.
Step 2: I pour raw cow milk ( or whole milk not treated with hormones) into the jar about two inches from the top.
Step 3: I put a small cut of cheesecloth over the top of the lid and secure it around the jar with a rubber band. It's not mandatory that cheesecloth is used. I've actually used a paper towel before. It's also common for people to use coffee filters. Basically, the demands are to keep pests out (gnats, flies, bugs) while still providing air.
Step 4: I set the jar in a dark corner on my kitchen counter and let it sit for 24 hours. After about 24 hours I will remove the cheesecloth and stir the milk around to test for desire thickness. If the milk is still very thin I will replace the cheesecloth and let it sit again for another 12 hours or so.
Step 5: At about 36 hours, 48 hours at most the milk is thick and is now considered Kefir.
Step 6: I rest a plastic colander/strainer over a bowl and pour the milk into the strainer. If it's really thick I may have to shake the colander a little bit. What remains in the strainer are only the Kefir
grains. I then put a lid on the quart jar and stick it in the fridge.
Make sure to use a plastic strainer or collander. You will see pictures all over the internet of people using metal ones-this is not a good idea. The kefir grains do better when not coming into contact with metal.
Step 7: I start the process all over again. Store the cultured milk, now Kefir, with a lid in the refridgerator until ready to use. The longest I've had my Kefir in the fridge before use is about ten days. Smell it and taste it if it's been over a week. I have eaten yogurt that was a month over its expiration date in the store. I'm not too worried about eating a product that has already been cultured after a while either.
This really makes a great addition to a morning meal and a great snack for any time during the day. I attribute the Kefir in our diet as the reason why neither my kids or myself have had any sort of bad stomach bug for a long time despite repeated exposure.
There are several ways to go about getting a Kefir starter. The best way is to ask all the "granola" "crazy" healthy people you know about getting some of their grains from them. My Green Giant sister-in-law was the generous one to share with me. Kefir grains multiply over time and Kefir fanatics, like myself, LOVE to share their grains and spread the Kefir love, so don't feel too funny about asking. Do feel funny if you start to become harassing. ;) Kefir reproduce at their own rate, so if you're in a hurry to get started because you're too excited to wait, then go with plan B.
The kefir lady is a great place http://www.kefirlady.com/ is a great place for Kefir starters. Other reliable starters can be found from Cultures for Health and Body Ecology. The Green Smoothie Girl occasionally has starters as well but they go fast. However you find your Kefir grains, "kefiring" is a Green Giant habit that is well worth the five minutes of actual man time it takes to make it.
TO SERVE:
Our most basic Kefir smoothie recipe is blending one frozen banana to about 10 oz Kefir. Blending peaches, strawberries, mangoes are all great choices. I like using frozen fruit for an icier texture. Yumm!!!
