Are we going to argue that the cow's diet in Europe somehow makes a difference in the taste of the milk used for the cheese? Because other than that, the process is exactly the same. I don't believe a connoisseur could tell the difference between a high quality North American cheese and its European equivalent.
Such ignorance...
By the way how the hell can you call Parmigiano if not Parmigiano? Cheese powder? And if i want some Pecorino Romano? Salty cheese powder?
I don't know... i'm totally ok with limiting the nomenclature of cheese in the US since it's known that the market is dominated italian fakes there but you have to have ready a good alternate name for it.
