To be fair, we should've filmed his whole process when he made 2 pizzas for himself and I. This particular stretch was just for showing off to my staff, hence the air spin.
But he did it like I've seen many others from Napoli - slap to about 7-8 inches, sauce and top, stretch while pulling/rotating onto the peel, stretch again to about 12 inches around, and fire in the oven. I personally go to 10", then stretch to 11" while loading onto on the peel.
PB - awesome, that is wonderful to hear and I look forward to finally meeting you!
