Pizza is the most globally recognized Italian food and the most thoroughly misrepresented, the product sold as "Italian pizza" in most of the world isn't Neapolitan pizza (the legal designation protected by the Associazione Verace Pizza Napoletana since 1984 and by EU Specialità Tradizionale Garantita registration since 2010), not Roman pizza, and not any other specific Italian tradition. It is a generic pizza concept inspired by Italian immigration to America in the late nineteenth and early twentieth century, developed in the specific conditions of New York, Chicago, and California according to local tastes and available ingredients, and then re-exported to Italy as a cultural reference point in a feedback loop that would amuse Neapolitans if they could be bothered to pay attention to it.
The Italian pizza landscape itself is more varied than almost any international visitor expects: five or six genuinely distinct regional pizza traditions, each with its own specific dough, fermentation, thickness, cooking method, and topping logic. Understanding the differences is the prerequisite for ordering well and for appreciating what you receive.

Italy's Pizza Traditions: A Complete Survey
Pizza Napoletana STG
The Neapolitan pizza, the original, the reference, the legally protected tradition, is defined by the AVPN (Associazione Verace Pizza Napoletana) specifications and the EU STG (Specialità Tradizionale Garantita) registration: Type 00 flour (or Type 0 with specific protein and ash content). The specific poolish or direct dough method with a minimum 8-hour fermentation (most serious Neapolitan pizzerias ferment 24-72 hours for flavor development). Hand-stretched disk (not rolled) of 22-35 cm diameter. Baked in a wood-burning forno napoletano at 430-480°C for 60-90 seconds. Producing the specific cornicione (thick charred rim, leopard-spotted with burn marks), the soft and slightly chewy center, and the specific combination of flavors from the high-temperature steam cooking. The two canonical Neapolitan pizzas: Margherita (tomato DOP San Marzano, fior di latte mozzarella or Mozzarella di Bufala, fresh basil, olive oil) and Marinara (tomato, garlic, oregano, olive oil, no cheese, the fishermen's pizza, eaten in port before refrigeration made cheese travel viable).
Pizza Romana al Taglio
Roman pizza by the slice, baked in large rectangular trays in an electric or deck oven, served cut into rectangles priced by weight. The dough: higher hydration than Neapolitan (70-80%), longer cold fermentation (24-72 hours), producing an open crumb with large bubbles and a crispy bottom. The Roman al taglio tradition has experienced a significant quality renaissance since 2010, the new-generation Roman al taglio pizzerias (Bonci's Pizzarium being the most internationally cited example, Via della Meloria 43, Rome) use long-fermented doughs, high-quality toppings, and seasonal ingredient combinations. Price: approximately €3-5 per 100g. The Roman tonda (round Roman pizza), thin, crispy, served whole, is different from both Neapolitan (thinner, crispier, less rim) and al taglio (different cooking vessel and fermentation).
Pizza Siciliana: Sfincione and Beyond
The Sicilian pizza tradition is the most ancient, the sfincione (from the Latin "spongia," sponge) of Palermo is a thick-based focaccia-style pizza with breadcrumbs, onion, tomato, caciocavallo cheese, and anchovy, baked in a rectangular tray and sold on the street since at least the medieval period. The sfincione barese (from Bari, Puglia, technically not Sicilian but in the same tradition) is thinner and uses different toppings. The specifically Sicilian aspect: the sfincione uses breadcrumbs as a textural element and the topping is more abundant and more complex than the Neapolitan approach.
Q&A: Italian Pizza
What is the difference between Neapolitan and New York pizza?
Four structural differences: flour (00 vs American bread flour, producing different gluten structures). Oven (wood-fired at 480°C vs gas at 260-290°C, producing different crust textures). Water (Neapolitan water mineral content affects gluten development. New York's water is notably soft, the "New York water" legend has some chemical basis). And serving format (Neapolitan individual whole pizza, New York by the slice). The result: Neapolitan pizza is soft, chewy, slightly wet in the center, quick to cool and become even softer. New York pizza is foldable (the famous New York fold), drier, reheats well, and functions as street food in ways that Neapolitan pizza does not.
Is pineapple on pizza a problem in Italy?
It is, in the specific sense that it doesn't exist on any Italian pizza tradition and that proposing it to a Neapolitan pizzaiolo produces a specific reaction that is diplomatically described as unwelcoming. Italian pizza isn't a customizable vehicle for toppings. It is a specific product with a defined topping logic, and the specific combination of the dough, the cooking temperature, and the topping proportions has been refined over generations. Ordering pineapple on pizza in Naples specifically is the equivalent of ordering a Big Mac at a starred restaurant, technically possible in some establishments, deeply wrong in spirit.
