NYC tap water wins again APR 23 2009
A year ago, I collected a bunch of links related to what makes NYC pizza taste like it does. New York's fantastic tap water was a leading candidate. In a recent blind taste test of identical pies, a panel of judges -- including some noted NYC pizza chefs -- chose a pizza made with NYC municipal water over those made from LA and Chicago water.
Also, I just ran across this map showing NYC pizzerias which are outfitted with coal ovens. There are many more than I would have thought.
