A three-layer insulation structure is the reason this outdoor pizza oven heats up quickly and reaches a maximum temperature of 930 degrees Fahrenheit. That heat level is the whole point of a dedicated pizza oven rather than a conventional one: at 930 degrees a fresh 12-inch pizza cooks in two to five minutes, fast enough that the crust chars and puffs before the toppings dry out. The 12 by 12 inch pizza stone underneath stores and returns that heat directly into the base, which is what produces a crisp bottom instead of a pale, soft one.Control and monitoring are handled without opening the chamber and dumping heat. A built-in thermometer reads in both Fahrenheit and Celsius so the oven can be brought to temperature before the first pizza goes in, and the removable door carries a check window for watching progress mid-bake. The firebox is heated with charcoal and wood pellets, and it is designed so that adding fuel during a session and dumping ashes afterward are both straightforward rather than requiring the oven be broken down.Pizza is not the limit; the chamber is also well suited to cooking steak, chicken, vegetables, and fish. The body is metal and stainless steel in black and silver, measuring 20 by 15 by 32.5 inches and weighing 31 pounds. Four foldable legs collapse and the chimney lifts off entirely, which makes storage and transport genuinely easy rather than a matter of finding somewhere to park a fixed unit. The outer surface is rustproof and cleans with a damp cloth.
