Firing a pizza oven involves preparing the oven floor, lighting kindling, and gradually building a fire with hardwood to reach the desired high temperature, typically ranging from 700 to 900 degrees Fahrenheit. It is crucial to distribute the burning wood evenly, allowing the oven to absorb the heat uniformly. Once the desired temperature is achieved, the fire is allowed to settle, and any remaining ash is removed with a pizza oven brush. This meticulous process ensures that the pizza oven is sufficiently heated and ready to create the optimal cooking environment for baking delicious, crispy, and flavorful pizzas with the desired crust texture.
