You’re never going to get a good pizza if your oven isn’t hot enough. It will have a floppy base and take ages to cook. As it needs to reach at least 350˚C (660˚F) to cook a pizza, it helps to know at what point your oven is at the optimum temperature.
It’s often a guessing game and one that you will get better at the more you use your pizza oven. But if you want to take the guesswork out of the equation, a built-in temperature gauge is a handy extra. If your pizza oven doesn’t have one, you can always invest in the best pizza oven accessories and buy a separate thermometer.
