Made this last night. Wow, what can I say. This is the flaky, crisp, tender crust that I've been looking for.
Of course, I did have issues, mostly mine. You said a hot oven, so I used my Blackstone at 600-625 degrees. Tried to par bake the first crust, blew up like a pita, even after docking it what I thought was excessive. Tore it up trying to get it off the stone, but flipped it over and topped the torn up side.
Made the second skin, and put it on a pizza pan to par bake. Worked much better. Let the skins cool and then made the better par baked skin the first pizza for the wife. You have to please her. She thought it was outstanding.
Used the torn up skin to make my pizza, and it was all I had hoped for. I did over bake it. I think the temp was way too high. Next time I'll lower the temp to around 550-575 degrees, and either lower the sugar or delete it all together.
I didn't get any pictures of the first pizza, but here's a half og mine showing the cracker crumbs I've been looking for.
