OK, I tried Paul's poly dough recipe yesterday. It worked great. It took about 11-12 cups of flour. I used very warm water, not hot. I was afraid of killing the yeast with hot water.
I made one loaf of bread right away. Julia, my picky eater, ate three pieces of buttered bread, and the whole loaf disappeared within about 30 minutes of cutting it, so I guess they liked it.
Then last night, I used some more of the dough to make pizza. No complaints there either. Next time, I will let the dough sit for a few minutes before I start shaping it for the pizza though. I noticed it got easier to work with as it warmed up.
I still have some dough in the fridge.
