At 80% does the dough almost spread itself in the pan? It looks almost like yogurt consistency.
If you are interested in what the dough balls looked like, I posted at Reply 46 what the one dough ball looked like when it was balled. http://www.pizzamaking.com/forum/index.php/topic,24649.msg253488.html#msg253488
And later in the same thread a photo of the second dough ball. In the same thread I posted that the dough balls were not that sticky. I am not sure, but think the Divella Semola di Grano Duro does absorb more of the formula water than other flours do, or either since the flour was old, that might have also helped. Earlier in Johnny's thread I have other photos and explanations if you didn't see them.
When the dough balls were cold, there was no problems spreading them in the steel pans. Those two dough balls acted normally when spreading. Cold dough is much easier to work with at a high hydration than warm dough. I think the dough balls did ferment more because of the higher hydration though. That is even the one with the salt added. The second skin in the pan fermented a lot when it was tempered for a longer period than the first one. I wish I would have taken a photo of that went it came out of the little proofer I use, but I jiggled it and it looked like jelly when it was warm, but it quickly fell a fair amount. I wish I would not have jiggled it.
I want to try another experiment with using the Divella Semola di Grano Duro flour, but less of that flour and more Occident flour to see what might happen. I really don't know, but don't think Occident flour alone can handle 80% hydration with my limited dough making skills in higher hydrations. I tried 85% hydration one time with the Occident flour on the other DS thread and had a mess with that dough.
