Giving Starter away on Craig's List
Every weekend, I bake 2-3 loaves of sourdough (usually whole wheat) for my family's weekly bread. I love sourdough, and I particularly love that I've figured out (finally) how to coax sour flavor out of our sweet New England microflora (long, cool bulk rise with a stiff starter).
I absolutely hate, however, having to throw away starter when I feed it. Drives me bannanas.
So I had an idea earlier this week. Why not place an ad on Craig's list and give it away? I came up with a quick ad: http://boston.craigslist.org/zip/155223285.html 
Less than 24 hours later, I've got 18 folks lined up, all of whom will gladly give my sourdough "waste" for the entire month of May a happy home. At this rate, I'll just have to put up one ad per month.
So now, I can make my sourdough guilt free. :-)
