Focaccia

Target 80% hydration · sheet pan · bake at 450°F

Focaccia is pan-baked flatbread with olive-oil-drenched crust, irregular large bubbles, and signature dimpled surface. 80% hydration produces the characteristic airy crumb. Top with olive oil, flaky salt, and optional herbs (rosemary) or toppings (tomato, olives). Bonci-style Roman focaccia uses 24h cold bulk; Genoese focaccia uses shorter 4-6h room temp proof. This formula follows the Genoese tradition — quicker schedule, still open crumb.

Technique

Mix everything at once (no autolyse). 3-4 stretch-and-folds. 3h bulk at 76°F. Heavily oil a quarter-sheet pan (at least 3 tbsp olive oil). Transfer dough, gently stretch to fill pan. Proof 90 min. Dimple with oiled fingertips to create deep wells. Drizzle olive oil over, sprinkle flaky salt. Bake at 450°F for 22-25 min until golden brown on top and bottom.

How the math works

Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.

Salt % is computed on total flour weight, not final-dough flour.
