In the video he says it's normal pizza dough.
I make something similar that's called a panuozzo.
It's just normal pizza dough, then stretched to be long and flat. I baked these today as my dough was over fermented and wouldn't have lived until tonight. I think normally it's made without oil and uses standard Neapolitan dough.
225g dough balls, 58% hydration, 3% EVO, 3% salt, they had doubled in volume.
I baked them for about 2 minutes at 400C.
I think the secret is quite a lot of heat from below, and flattened evenly, neither too thin nor too think.
Next time I'll try making these instead.
