Ahhh so this explains the Parmesan cartel. If you don't know, the only "true" Parmesan comes from Italy and there's a cartel of pretty ruthless (legally, not like drug cartels or anything lol) people that try their best to keep it that way.
There was a bunch of drama once about a guy in the US that was a cheese making hobiest that tried to make his own parmesan using some methods he thought of. The Parmesan cartel in Italy sent him a cease and decist letter.
