I did a search, but there are too many results to pour through. I quit after 7.
I made a batch in my bread machine, used a bit for one pizza, and then accidentally forgot it in the unplugged machine. The next day, about 12-13 hours later, I remembered. It had risen again, and when I pulled it out, it emited a sour odor. Is this just a literal "sour dough", or should I discard it. I don't mind the taste of sour dough, BTW.
