You can freeze extra dough balls for up to a month. Just allow them to rest in the refrigerator for 24 hours before using.
We use a pizza stone to bake our pizza, but we don’t have a proper pizza peel. So instead we use an upside down cookie sheet well coated with sesame seeds (corn meal or semolina flour work well too). Make sure the dough is well coated on the bottom or it will stick to the cookie sheet.
