Recap ;)

Napoli => The city

Napoletano => From Napoli, to indicate the people or as adjective

Napoletana => Same as above, but female.

"Pizza" is a female name, so "Pizza Napoletana".

However, seems delicious!

Do you know that in a traditional special recipe the "cornicione", the inflated pasta around, is filled with ricotta? Try it! (Ricotta, not mozzarella or cheese!).
