I just ordered The Art of Fermentation by Sandor Katz. I can't wait to flip through the tome, mouth watering or nose wrinkling at the various fermented creations to be found within. I admit I'm taking the whole fermenting thing slow. I've experimented with quite a few recipes in Katz' primer, Wild Fermentation, and have jars of yogurt, kimchi, kraut, kombucha, and pickles in my stash. I figure I'll perfect my skills with the basics before moving to stuff like Chicha (read the recipe- I dare you) and whatever else might be awaiting in Katz' new book. But I love my kombucha. Making it yourself is not only much cheaper but you can create the flavors and sweetness that appeal to you! Besides, who can resist the science-experiment-like draw of this mushroom/yeast bevvie? Here's how I make my kombucha (based on the recipe in Wild Fermentation) (I usually double or quadruple the recipe I drink so much!):
Grab a 1 quart mason jar. Steep 2 black tea bags in 1 quart of hot water for at least 20 minutes. Remove tea bags. Add 1/4 cup sugar and stir until dissolved. Let cool to the point where you can stick your hand in without it hurting. (Very scientific) About 100 degrees. Add a kombucha mother (get one from a friend or buy at a place like OB People's Co-op), translucent side down, along with some of the kombucha the mother was stored in (or apple cider vinegar in a pinch). Cover mouth of jar with cheesecloth and store in a warm spot (70-85 degrees). Let it hang out for about a week, longer if you want it less sweet, more acidic. Once it tastes good to you, store it covered in the fridge. Start a new batch and add one of the mothers (the mother you used will grow another "skin." Peel this off and use either one.) Enjoy!
