Add packet contents of Little Sioux Kitchen Neapolitan-Style Pizza Dough Mix and water to a large glass bowl. Stir until flour is incorporated. Cover with plastic wrap and let sit at room temperature for 24 hours or a minimum of 18 hours.
Move oven rack to lowest position and preheat to 500℉. If using a pizza steel, let it preheat for at least 15 minutes or up to 1 hour.
Spread flour onto a clean surface. Transfer half of the dough to the floured surface; lightly coat the dough with a little flour. Press dough out starting from the middle and try not to fuss with the outer crust so it is airy when baked. The goal is a 12-in diameter (thin in the middle with a thicker outer crust). Transfer dough onto parchment paper.
Add toppings and bake at 500℉ (lowest rack) for 10-12 minutes, but begin checking for doneness around 8 minutes. It is done when the bottom is a deep golden brown and the toppings have melted. Repeat with remaining dough.
Note: the pizza pictured was topped with canned crushed tomatoes, shredded Italian cheese, fresh mozzarella cheese, and pepperoni. Topped with fresh basil leaves after baked.
Also: if you prefer thin crust pizza this dough works great! Just roll it out very thinly. Makes about 4 pizzas.
