Origins

Hailing from Naples, Italy, the Neapolitan pizza is often regarded as the mother of pizza. It was inscribed on UNESCO's Intangible Cultural Heritage list, emphasizing its cultural significance.

Characteristics

• Texture & Flavor:
  • Crust: Soft, tender, with a characteristic airy crumb.
  • Flavor: Mild, slightly tangy from fermentation.
• Baking Method: Traditional wood-fired oven at extremely high temperatures (around 900°F / 480°C).

Unique Factors

• Cooking Time: 60-90 seconds for that perfect blistered surface.
• Size: Usually around 10-12 inches diameter.
