Neapolitan pizza, Italy

Neapolitan pizza isn't always so big -- but whatever its size it's delicious.

The best pizza was and still is the simple Neapolitan, an invention now protected by its own trade association that insists on sea salt, high-grade wheat flour, the use of only three types of fresh tomatoes, hand-rolled dough and the strict use of a wood-fired oven, among other quality stipulations.
With just a few ingredients -- dough, tomatoes, olive oil, salt and basil (the marinara pizza does not even contain cheese) -- the Neapolitans created a food that few make properly, but everyone enjoys thoroughly.
