The dough gets its slightly tangy flavor from a "sponge" (a mixture of warm water, yeast, and flour thats allowed to ferment). Timing note: The sponge needs to rest overnight; the dough needs to rise for about eight hours.
Test-kitchen tip:
To speed things up, you can bake two pizzas at the same time. To ensure even cooking, be sure to reverse the position of the baking sheets after 8 minutes. Baking two pizzas at once may take longer than 14 minutes.
