I don't bother sterilizing any more. I'm glad to read this. I used to "make yogurt" by mixing a small container of yogurt into a gallon of milk and leaving it out on the counter for a day. The result was perfectly cromulent yogurt. Then well-meaning friends urged me to worry about sterilization, and I haven't made it since...
