I use a baking steel. After the oven sits at 475-500, change to a broiler, steel on the top rack. You can cook on the steel or use a steel pan, like the deep dish types sold by Chicago Metallics. Neapolitan styles are harder to reproduce in a home oven, but by cranking the heat up, you can get close; those typically are cooked an a stone or steel at 550°F or higher. Use fewer toppings.
A baking steel won’t crack. Stones can fracture if temperatures or radiant heat builds up too fast.
Salt in the dough is primarily to slow the yeast down.
From my father’s recipe:
MAKING THE DOUGH
(I usually make dough and sauce the Wednesday after I’ve used up the last frozen portion for use the following Saturday which is pizza day for
us.)
6 cups of flour (I use King Arthur’s bread flour for best results) 2 cups warm (105 deg.) Water.
2 packets of instant yeast. I prefer Red stars platinum superior baking yeast. I do not use Fleischmann’s pizza crust yeast.
1 teaspoons salt
1 tbs. olive oil (some use more but I don’t) 1⁄4 teaspoon sugar
A large ss mixing bowl.
Put warm water in the bowl, add the yeast and mix using a whisk. Add 1 cup of the flour, the olive oil, salt and sugar.
Whisk until all is reasonably incorporated. Let it set for about 15 minutes.
Start adding the rest of the flour. I use a wooden spoon to mix until I see I need to use my hands. Keep a lot of flour on hand.
Knead the dough until it’s reasonably homogeneous, soft, smooth and stretchy. But don’t overwork it.
Put the dough into a smaller bowl lightly coated with olive oil. Should look like a mildly flattened bowling ball.
Cover bowl with a dishtowel and place in a warm (not hot!) spot.
Check on it every half hour or so. Dough should rise to the top of the bowl. When it does, coat hands with flour and deflate it.
At this point, I put the dough ball in the fridge overnight. Make 16 oz. dough balls the next day, after the dough has chilled. The individual dough balls, each for a 14 inch pizza, go back in the fridge (covered) until the next day.
This makes a"Bar" or New England style of pizza, with a crisp crust that doesn’t sag. You may be able to delete the salt from the dough; I don’t know. These pizzas can hold a lot of toppings. I make this type in a pan. Sometimes, the broiler is needed to roast the toppings after the crust is nearly done.
The 3-day ferment gives the dough a great sourdough aroma and flavor. Plus, the gluten relaxes, making the dough much easier to stretch. Allow extra time, after spreading, for the dough to rise again, covered in the pan, before topping.
My Italian grandparents ran an Italian cafe in MA, making who knows how many pizzas. My Dad and his brother worked in the cafe. The food there was locally famous. They adapted pizza to American tastes, with more toppings.
