Olive oil, flaky salt, and fresh rosemary atop a pillowy, dimpled focaccia — perfect for sharing.
Stir the starter into the water, add the flour, and mix until combined. Rest 30 minutes, then add the salt.
Over the next 2 hours, do 3 or 4 coil folds. The dough should become glossy and stretchy.
Leave the dough until bubbly and expanded, usually another 2 to 3 hours at room temperature.
Pour olive oil into a baking pan, ease in the dough, and gently stretch it toward the corners. After a short rest, dimple the surface with oiled fingers.
Scatter rosemary and flaky salt over the top. Bake at 220C for 22 to 25 minutes until the edges are crisp and the center is golden.
