Hey Craig -- Just following up on my previous query regarding the fragility of the dough when stretching. I had at it again but haven't had time to post. I tried in balls for ~12 hours and it was still pretty similar, hard to work with. Seems the gluten development is just not as strong as I find with ADY. I admittedly had a bit of trouble keeping a steady temp in the bulk -- started too cold, around 61F but warmed up from there - I would say the avg was around 65F when all said and done, before I balled and started to warm up further (high 60s, low 70s) before launch.
My starter is quite strong when I mix, so perhaps it's my method. Would an increase in mix time help? Perhaps I'm not balling tight enough...? I realize it's hard for you to say without seeing but anything else you can think of? Pics below start with the end of bulk, then dough ball activity before launch (looks quite active), then the finished product.
I am thinking of adding a bit of ADY the next time so that it's not such a struggle, though I know I may get shunned for that around these parts!
