Some feature large golden patches, while others have a smooth, uniform white surface.
These differences can reflect deliberate choices made by the restaurant.
Professional kitchens often select cheese based on specific performance characteristics.
The cheese must melt appropriately, create an appealing texture, and remain consistent across many pizzas.
Manufacturers also evaluate how cheese stretches, browns, releases fat, and forms blisters.
These qualities influence how the finished pizza looks and tastes.
Different pizza styles, different expectations
Consider a traditional Neapolitan-style pizza.
It is often baked rapidly at very high temperatures.
Its crust may develop dark, scattered spots, and fresh mozzarella may form soft, irregular patches across the surface.
By contrast, a typical American-style delivery pizza may use low-moisture mozzarella designed to melt into a more continuous layer.
A New York-style slice might feature golden cheese with visible areas of browning.
A deep-dish pizza may have a very different cheese arrangement and heat exposure.
