Pizza is interesting. Last year I spoke with the head of r&d of a major water filtering company based in italy, the birthplace of pizza.<p>A little unknown fact is Water quality makes a difference on the taste of pizza. There is a saying in the states that you cant replicate true new york pizza unless you use new york water, etc.<p>Good pizza water tastes awful if you drank it as is. I dont recall which elements were added inside of it, but its there. Another interesting tidbit is pizza quality is sometimes compared to coffee quality for water enthusiasts.<p>Sometimes called "waves". A first wave coffee shop is like getting a awful espresso shot at a hotel. 2nd and 3rd wave is like starbucks. 4th wave is when a coffee shop sources their own products and knows the history behind its goods. 5th wave is everything - these are generallly operated by famous baristas who have basic chemistry knowledge and expertise operating a espresso machine.<p>Pizza is the similar in ratings to coffee in this regard.
