Kombucha!

I just started another jar of kombucha. What is kombucha? It's a cultured, fermented tea.
 You take a "mother" (the culture. It has several names: mother, scobie, mushroom, starter), put it in a large glass jar (you have to use glass), brew 3 quarts of tea (green or black), add 1 cup of sugar, let it cool to room temp. and add it to the large jar.
 Cover the top of the jar with a coffee filter, paper towel, etc, and put a rubber band around it to hold it in place.
  Let it sit for 1 to 2 weeks. The longer you let it sit, the less sugary it will be. You can let it sit for longer than that, but I don't think it would taste that great. Kombucha also has a very small alcohol content, and the longer you let it sit, the greater that content becomes.
  When it's done, put it into glass jars, and put in your refrigerator. Make sure to leave at least a cup in the big glass jar for the starter, since it will die if it dries out.
 It's super easy. You can get a culture from http://www.culturesforhealth.com/, or, if you live near me, and know me, you can get one from me. They reproduce themselves...a lot.
 In the last picture you can see that mine has 3 connected. You just separate them, and voila, you have three starters. :)
