Mix
Mix the active sourdough starter, warm water and bread flour until combined. Cover and rest 30 minutes.
Time: 30 minAdd salt and oil
Add the 9 g salt and 22–23 g olive oil. Pinch and squeeze them into the dough until incorporated, then rest another 30 minutes.
Time: 30 minBuild strength
Complete 3 stretch-and-fold sets, spaced 30 minutes apart.
Time: 30 minBulk ferment
Continue bulk fermentation until the dough is visibly airy, puffy, bubbly and noticeably jiggly. Watch the dough rather than only the clock.
Pan the dough
Generously oil one large pan, approximately 14.8 × 9.6 inches. Transfer the dough to the pan and rest 20–30 minutes, then gently stretch it toward the edges. If it pulls back, rest another 15–20 minutes and stretch again.
Time: 20–30 minFinal proof
Cover and final-proof until the dough is puffy and bubbly, usually 45–90 minutes depending on room temperature and starter activity.
Time: 45–90 minTop the pizza
Oil your fingertips and lightly dimple the dough. Add a thin layer of pizza sauce, mozzarella and your preferred toppings. Keep the toppings reasonably light so the thinner focaccia base stays crisp.
Bake
Bake at 425°F / 218°C until the bottom and edges are crisp and the dough is cooked through, generally 22–30 minutes.
Time: 22–30 minCool briefly and slice
Let the pizza rest in the pan for about 5 minutes, then transfer it to a rack or cutting board before slicing.
Time: 5 min
