mzimm, So I had some AP flour to use up and some time so I concocted a faux sourdough dough to try out using sour cream and vinegar with a bit of water. 60% hydration, no rise, rolled it out, topped with mushrooms, onion and cheese. Not bad, not great, I was surprised it really didn't taste all that sour. May delete the water all together although the cream made it bake quite differently. Still think a hour or so rise would help the taste but I'm not done yet.
