Well, one thing is for sure... NY does not hold rights to the only purified water in the U.S. There's tons of it available at any local store in the U.S. these days, and there are plenty of excellent purified water stores in local neighborhoods... we all have mountain spring water available at our finger tips as well. I'm drinking some mountain lake water right now, and I have natural springs water as well.. There's plenty of choices available to all of us.
I was happy to see Tony Gemignani in his recent book ( http://www.pizzamaking.com/forum/index.php/topic,1909.0.html
) spent no more than 1 paragraph on the subject as he deported water accordingly.
I have to admit though, I wish that I could make any style of pizza by getting access to their purified water system, and maybe even the pipes that go into Totonno's.
As for cheese, we certainly know from all the posts that there is no one single cheese employed in New York. Di Fara's, for example, mixes 75% mozzarella di bufala from Casapulla, just outside Naples, and 25% full fat Grande Mozzarella. He also mixes his flour 75% 00 from Italy with 25% American high gluten, and he uses Marzano tomatoes, along with his herbs.
Just as preferences vary widely in New York pizza among the consumers, so obviously do the ingredients and processes by which they follow.
Bottom line: When Di Fara's mixture is divulged in American Pie, or other secrets are revealed by the World Pizza Champion team and Tony Gemignani, are we now in a position to produce exact replicas? NO, because the only statement that can hold true as a standard for any pizza in the world, as well as for ALL of us, is the one that Chris Bianco stated in American Pie... the secret is in ME. And here's a guy out in the middle of the desert who is widely acclaimed for his attitude to do business locally from farmers and others, whenever possible.
By making pizza at home, we too have the exact opportunity as Bianco or DeMarco to find ingredients that meet our exact taste buds, which in some cases may be in our own back yard... including the water.
