Oil and sugar. Traditional Italian pizza dough is made with just flour, water, salt, and yeast. The pizzas are baked at like 12,000 degrees and give you this amazingly crispy experience. (just kidding, more like 900 degrees.) Since most of us have ovens that go to 550 degrees max, we add a couple ingredients to the dough to help make it extra crispy: Oil. Oil conducts heat. If you added oil to your dough and cooked it at 900 degrees, it would burn (oil conducts heat!) We are baking at 500ish. That heat-conducting oil helps our pizza crisp! Sugar. Sugar is added to help the pizza get brown on the edges, and to help the dough crisp in the oven. Sugar does the same thing in chocolate chip cookies! (Of course, we're not adding quite as much to our pizza dough.) Rolling out the dough extra thin is another way to get super crispy pizza crust. Today's recipe makes 2 pizzas, but if you like extra crispy crust, divide the dough into 3 and roll it out thin!
