i think i agree on the 2 types. i worked there when i was a kid a long time ago as a busboy/dishwasher etc.... had to help staff prep sometimes. i ground blocks of cheese cut into 4ths size of a stick of butter, put them through a meat grinder, it makes kinda pellets sometimes, so its not a flake like a grated mozz. i remember it being such a dry cheese but tasted very good. salty, my taste memory says parmesan, although i had never heard of asiago back then.....
i think scamorza, and parm right now. sauce is still unknown to me, crust still haven't tried. great pics!!! thank you!
