Oh Bruno, you have explained very well how things are - I'm not able to translate some things so I give up after twenty minutes thinking at it

Moreover, I dont' think someone knows about calzone! It's my favourite 'type' of pizza. The simple one has mozzarella and cooked ham inside, and tomato sauce on top.

For the rest, you're right on mozzarella and simplicity - I have to check well what 'rest of the world' guys intends for 'pepperoni'...
