Is this a sign of overproofing?
Hi - been a long time since I posted here - been getting back into breadmaking after several years hiatus, and decided to try some sourdough - specifically the Tartine recipe, after I tried a loaf a friend of mine made.
I actually made it two times already - the first with a great success, the second was still good, but not as successful as the first. I just tried for a third time, and something happened with the dough that caused me to just throw the whole thing out.
Basically, everything seems fine during the autolyse period, and then for the first few stretch and folds. But but the 3rd hour, the dough seemed to start to break down somehow. It was actually getting more wet feeling as time went on. The dough had some elasticity, but was almost turned into a thick batter type consistency by the end of the 4th hr.
I turned it onto my work surface and started to try to shape it, but it clearly was just not right - nothing like my first two attempts. I thought maybe I'd try to slap it around and knead it a bit, but that seemed to just make it worse. After 10-15 minutes, it was literally like pancake batter and I just tossed it.
I have no idea what went wrong here. The starter was clearly working - the dough increased in volume by about 30% and was bubbling like crazy towards the end. I wonder if I just over-did the rise period?
A few notes about my setup - I do the rises in my oven with the light on. I wonder if it was just too warm in there? Could that cause something like this? Also, I do my stretch and folds in a stainless steel bowl - could that have anything to do with it? Other than that I'm pretty much following the formula exactly. 750 gm of water, 1000 gm of flour (900 gm bread/100gm ww), 200 gm of starter.
Is it possible the starter itself was too hydrated? I fed it early this morning and it had been sitting out at room temp all day, for about 10 hrs.
I just want to get some ideas of what I should try to change up for my next attempt. There are only so many variables here, just got to pick one!
Thanks in advance for any tips.
