uk1 you have some amazing info in here. I've been making pizzas on a pizza pan (the kind with holes in it) for years, but I can't wait to try your biga dough on a stone... should be a dandy.
I spent all night last night making a huge vat of sauce base (I like to incorporate onions into mine, but to each their own, right?), and as soon as my stone arrives, it's pizza time!
