Yogurt-based sourdough smells like alcohol I'm following this yogurt-based sourdough recipe, and (right now) at the 18-hour mark, it (the dough) smells like alcohol. Is this a bad sign, that it should not be consumed? And, moreover, is this recipe perhaps dangerous for leaving yogurt out for extended periods of time? Or will the baking process make it safe to eat?

Note: I'm aware that when sourdough starter smells like alcohol, it needs to be fed. But this is actual dough and not starter, which is cause for my concern.

Edit: Finished baking it. Smelled sour-dough-y and fine so I tried a bit. Not as good as regular sourdough but I think the alcohol-smelling issue was actually a non-issue.
You should try the same recipe again, but use a cloth instead of plastic wrap to cover your dough for the fermentation period.  The alcohol smell is the ethanol the yeast is producing, and in my own experience the more anaerobic the greater the level of ethanol produced.
