A home oven isn’t designed so well for cooking pizza as it isn’t hot enough and doesn’t have a hot surface to cook pizza on. That’s where a pizza stone comes in – it mimics the effects of a traditional pizza oven by turning into a red hot surface to cook pizza. The stone also draws moisture away to make the crust crispy, much like the bricks would in a brick oven. The result is a pizza with a delicious crispy base. Often when you cook on a cold, thin, baking sheet you will end up with a doughy, undercooked pizza so this problem is fixed with the stone. A newer invention is the pizza steel. This is a quarter inch thick piece of steel which works the same way as a pizza stone. Except the steel conducts heat better so it heats up faster, and then transfers more heat to the pizza, making it crispier and cooking faster. An added bonus is that they don’t crack from thermal shock. They are slightly more expensive but will last a lifetime. I have this pizza steel and can fully recommend it (click to see on Amazon). If you’d rather get something a bit cheaper, then at least get a pizza stone made of cordierite like this one from Amazon. It is less likely to crack like other pizza stones.
