Olive and rosemary focaccia
1½ hours, plus cooling time
Makes 1 focaccia; each focaccia yields 8 slices.
2 ounces low-moisture mozzarella, cut into generous ½-inch cubes
40 pitted Ascolana olives (or another large pitted green olive)
Olive oil for brushing
20 tufts fresh rosemary
Scant ½ teaspoon Maldon sea salt, or another large flake sea salt
1. Heat the oven to 450 degrees.
Remove the dishcloth from the top of one of the focaccias and, using your fingertips, gently tap down on the focaccia with about 5 light strokes to nudge it toward the edge of the pan; it still might not reach the edges, but don't worry.
2. One at a time,
push the mozzarella cubes into the focaccia dough while simultaneously pushing outward to encourage the dough toward the edge of the pan, arranging the cubes evenly over the surface of the dough and pressing them so deep they are almost flush with its surface.
3. Do the same
with the olives, arranging them in circular rows between the cheese cubes and pressing them down into the dough and slightly outward.
4. Brush the surface generously
with olive oil, then press the rosemary tufts into the dough. Sprinkle over the sea salt. Set the focaccia aside until it is risen and puffed around the toppings, about 30 minutes.
5. Place the focaccia
on the center rack of the oven and bake until crisp and golden-brown, 30 to 40 minutes. The focaccia should have risen almost to the top of the pan, and the cheese will be crisp and browned.
6. Move the pan
to the bottom of the oven and continue to bake until the bottom crust of the focaccia is deep golden and crisp to the touch, about 5 minutes more.
7. Remove the pan
from the oven and remove the focaccia from the pan to a wire rack (use a fork to gently lift and slide the focaccia out of the pan, careful of any hot oil that may still be at the bottom of the pan). Brush the surface of the focaccia once more with olive oil. Set the focaccia aside to cool slightly — or as long as you can resist it.
8. Transfer the focaccia
to a cutting board. Halve the focaccia using a long knife, then cut one-half into 4 wedges (don't cut the other half until you are ready to eat it).
