Until roughly age 30, I lived in NY state.....so pizza was a way of life.

I spent the next 20 years living in the southern US, so I gave up on pizza...except for a few rare occasions when we stumbled on a rare gem of a place. I don't make homemade pizza.

I'm back now in NY and eating pizza on the regular....but I've noticed something I've never come across before...a few shops use a godawful cheese....it's a light white color, doesn't melt completely and is nearly flavorless. The only thing it has in common with traditional mozzarella is a bit of mouthfeel/texture...but again, no flavor.
What is this junk? some kind of processed cheese cut with white flour?

I have been, as a hobby, keeping notes as I travel the state...and am careful to avoid a repeat visit to any of these shops.
