Homemade Kefir - cooking recipe

Ingredients

1 tablespoon kefir, grains (looks like little pieces of cauliflower)
1 quart whole milk

Preparation

Put kefir in glass jar and fill almost full with the whole milk (organic, non-pasteurized is preferable).
Cover with a clean cloth and place on the counter.
Wait 1 to 2 days, stirring periodically with a PLASTIC spoon (not metal).
When thick, strain out the kefir grains with a plastic strainer. Don't smash the grains.
Place grains in a clean jar and repeat.
You can cut down the tang of the kefir by '2nd fermenting': After removing grains, put 1-2 slices of lemon or lime peel or a vanilla bean back in the jar with the kefir. Cover and let sit on counter another day. After removing the peel/bean, taste the kefir. If it is to your liking, then cover with a plastic lid and put in fridge until ready to drink. If not, let sit a little longer with the peel/bean.
NOTE: If you run out of milk or will be out of town, place grains in a glass jar and cover with milk. Put a lid on jar and keep in fridge until ready to use again (they should be okay for a week or two, but will need fresh milk to feed on then.).
