Then again, there are many strange recipes masquerading as pizza around the world.
Here are a ten of the most deviant and, dare we say, delicious?

Why have one classic Italian dish when you can have two simultaneously?
Originating in the US, home to such delicious and faux-Italian specialties such as 'pasta Alfredo' and spaghetti with meatballs, this carb-rich pizza is fine fodder for hungover students but will surely leave the average Neapolitan nonplussed.
The Local is unaware of pasta being used in Italy as a pizza topping, but in many areas of the country waste-busting recipes use leftover spaghetti as a pizza base.
Several Costa Rican pizza restaurants list 'coconut' as a pizza topping. Home to such a rich biodiversity, Costa Ricans are clearly prepared to experiment with what passes as a pizza topping, and why not?
Another decidedly un-Italian thing to do with your pizza is cover it with doner meat – tempting though it may be in the early hours of the morning, when slightly inebriated.
The kebab pizza is an international dish which seemingly originated in Sweden and combines the cuisines of Italy and Turkey in a way that could horrify both Italians and Turks alike.
The much maligned deep-fried pizza is essential eating for any street-foodie worth their salt in Scotland.
It can normally be found on the menu in most chip shops and anyone willing to give it a try will be offered the choice of having their pizza deep-fried either with or without batter.
In the end it makes little difference. It is a dish so calorific that you can actually feel the years of your life slipping away as you scoff.
But it's not only popular in Scotland.
Similar versions of the dish do exist in italy, most commonly under the guise of panzerotti in Naples, where disks of deep-fried pizza dough are topped with cheese and ham and served from carts. Buon Appetito!

Another creation from the US, where the corndog is seen both as a popular snack and legitimate pizza topping.
For those of you who have never had the pleasure of tasting one, it is a sausage coated in a thick layer of cornmeal batter on a stick.
Just think of it as the all-American version of pizza con salsiccia....
The Mockba is Russia's answer to the Quattro Formaggi, except instead of being topped with four delicious cheeses, it's topped with four types of fish and is served cold – much like revenge.
Sardines, mackerel, salmon and tuna make the mockba a fishy feast for the taste buds and a terrible meal choice if you're on a Russian first date.
Plenty of real Italian pizzas do use fish – but not in such overwhelming quantities. In Italy, fish is used sparingly on pizza and the combination of cheese and fish is generally regarded as a bit of a food taboo.

Mizza may only be one consonant away from pizza – but there is a whole world of difference between the South Korea's mizza and the Italian pizza.
The mizza has a dough base, but has a layer of compounded aromatic rice instead of the traditional tomato sauce. The bed of rice is then topped with cheese, veggetables and meat.
When in Seoul...
Vending machine pizza
Several companies now make pizza vending machines that are able to knead your dough, choose your toppings and cook your pizza in less than five minutes before presenting you with a steaming box of freshly baked goodness.
While it may sound like sacrilege – the idea is quickly catching on and there are several of the machines already operating in Italy...
La tarte flambèe
France's answer to the Italian pizza may have a sophisticated name but it is really a super-simple and self-indulgent treat.
La tarte flambèe would struggle to be more Gallic if it tried. Featuring a crêpe-like base, which is topped with crème fraische, bacon and onions, it is a popular dish in the Alsace region of the country.
Hot dog stuffed crust and shrimp tempura mayonnaise
We've seen some pretty wacky pizzas from around the world so far, but nothing can compete with this incredible creation, reportedly on the menu in a leading pizza franchise in China.
This Chinese favourite consists of a hot dog stuffed crust, encircling a cheese and tomato pizza that is then heaped with with deep-fried shrimp and covered in swirls of mayonnaise.
Have you tried any of these wacky pizzas? Perhaps you've found a more un-Italian pizza on your travels – tell us about it in the comments below!
