Although it seems like a long first rise, the recipe is pretty accurate here. Plan out the following day to allow for enough time. Before baking, I brushed the loaf with infused rosemary olive oil and a little sea salt. Use your favorite olive oil — or nothing at all.
In a medium bowl, stir together the flour, olives, and yeast. Add the water and, with your hands, mix until the dough is wet and sticky, about 30 seconds. Cover the bowl and let sit at room temperature until the surface is dotted with bubbles and the dough is more than doubled in size, 12 to 18 hours.
When the first rise is complete, dust a work surface with flour. Gently scrape the dough out of the bowl in one piece–can use a dough scraper or spatula here. Lift the edges of the dough in toward the center and nudge and tuck them in to make it round.
Place a tea towel on your counter and generously dust it with wheat bran, cornmeal, or flour. Gently place the dough on the towel, seam side down. If the dough is tacky, dust the top lightly with wheat bran, cornmeal, or flour. Fold the ends of the tea towel loosely over the dough to cover it and place it in a warm, draft-free spot to rise for 1 to 2 hours. The dough is ready when it is almost doubled. If you gently poke it with your finger, it should hold the impression. If it springs back, let it rise for another 15 minutes.
Half an hour before the end of the second rise, preheat the oven to 475 degrees F, with a rack in the lower third, and place a covered 4 1/2 – to 5 1/2 -quart heavy pot in the center of the rack. Remove the preheated pot from the oven and uncover it. Unfold the tea towel and quickly but gently invert the dough into the pot, seam side up. Brush lightly with olive oil and sprinkle with sea salt. Cover the pot and bake for 30 minutes. *** (see note)
Remove the lid and continue baking until the bread is a deep chestnut color but not burnt, 15 to 30 minutes more. Use a heatproof spatula or pot holders to gently lift the bread out of the pot and place it on a rack to cool thoroughly.
***If using Le Creuset or similar pot, remember to screw off the knob on top of the lid — it’s not meant to withstand quite that much heat.
