Do I need a pizza stone or steel?
No, but heat helps. A pizza steel is the fastest route to a crisp bottom, but you can absolutely use a cast iron skillet or an upside-down sheet pan. Just preheat whatever you are using so the dough hits a hot surface.
My dough is sticky. Did I mess up?
Probably not. Sourdough pizza dough should be a bit tacky, especially early on. Use wet hands for folds, and use flour or semolina when shaping. If it is truly soupy and impossible to handle, add 1 to 2 tablespoons flour during the first hour of resting.
Can I make this with discard?
Use active starter for the timeline in this recipe. Discard can work, but the rise will be slower and less predictable. If you want to use discard, plan on a longer ferment and rely on the dough looking puffy rather than the clock.
Why is my crust pale?
Usually one of three things: oven not hot enough, baking surface not preheated long enough, or too much sauce and toppings cooling everything down. Go hotter, preheat longer, and keep toppings lighter.
How do I get those bubbly, blistered edges?
High heat, a well-fermented dough, and a little patience. Stretch gently so you keep the gas in the rim, then bake on a very hot surface. Also, do not roll the dough. Rolling is a bubble-pop party.
My oven only goes to 450°F or 475°F. Can I still do this?
Yes. Preheat longer, and bake a bit longer. Give your stone or steel at least 60 minutes to heat soak, and plan on 10 to 14 minutes of bake time. If you want more color, use the broiler at the end and babysit it like it owes you money.
