Pizza comes in many shapes and sizes depending on when and where a particular style developed. This tour hits three different versions of pizza from three different origin points. We'll talk about how the history and technology of each is instrumental in the resulting slice. Oh, and we'll eat all of them and we go!

The day starts with the oldest version of pizza, which is barely recognizable as such judging by today's standards. Next we try a classic Neapolitan pizza margherita with creamy mozzarella and bright tomatoes, followed by something I've only seen in Sicily and a couple tiny spots in NYC. Totally tasty!
