Here's how pizza is served in 21 different locations around the world

One of the best parts about travelling the world is getting to try different culinary specialties, and it seems like nearly every country has their own version of pizza. 

However, it might not be the typical tomato sauce, cheese, and bread combo you recognise.

From traditional Margarita pizza from Naples to a sweet and spicy banana curry pizza in Sweden, here are 23 types of pizza you can find around the world. 

Pizza is taken so seriously in Naples, Italy, that there is an organisation called that Associazione Verace Pizza Napoletana that's devoted to upholding its authenticity. Rules specify that pizza should be no more than 2 millimetres thick and baked for 60-90 seconds in a a 485 °C stone oven with an oak-wood fire. Classic Neapolitan pies have a chewy crust and are usually topped with fresh artisanal ingredients, like tomato mozzarella, fresh basil, and garlic.

In New Haven, Connecticut, pizza, or apizza, is cooked in an intensely hot brick oven to produce a more charred and crispy thin crust. These pizzas tend to include less cheese, and the 'white clam pie' invented by Frank Pepe's Pizzeria Napoletana, has become a staple with little neck clams smothered in olive oil, oregano, grated cheese, and chopped garlic.

Finland's Pizza Berlusconi is made of smoked reindeer, tomato, cheese, chanterelle, and red onions. The pizza got its name in 2008, after Italian Prime Minister Silvio Berlusconi made a comment about tasting Finnish cuisine. It won the America's Plate International pizza contest in New York that year.

Chicago, Illinois, is famous for its deep-dish pizzas, which are baked in a specialised, round pan and loaded with cheese and chunky tomato sauce.

Mayo Jaga is one of the pizzas you'll find in Japan. It is made with tomato sauce and topped with onions, corn, potato, pancetta, paprika and mayonnaise.

Thunfisch, or tuna fish pizza, is a popular choice in Germany. It typically includes tuna, tomato sauce, peppers, onions, cheese, and oregano.

In Pakistan, Chicken Tikka, chicken seasoned in chilli, is a popular topping in addition to sausage-based pizzas.

Frozen pizza is deep fried to create an insanely delicious slice that's popular in places like Glasgow and Fife in Scotland.

In Sweden, kebab pizza includes kebab meat, a yogurt sauce, a variety of pickled salads, and sometimes lettuce.
