Uncover, deflate and transfer the dough onto a flat surface.
Start forming your semolina bread by cutting the dough into two portions, then cut one of them into two smaller parts.
Form a rectangular log from the bigger half of the dough and place it on top of a baking sheet (and tray) that's generously dusted with flour.
Form a log of about 20-inch long for one of smaller dough portions and roll each end towards the center; on the opposite side --- forming an inverted 'S.'
Place it on top of the baking tray as well and brush it with water.
Sprinkle the dough with sesame seeds and do the same for the rest.
Using a sharp knife, create a cut on top of the pane Siciliano that's shaped into a rectangular dough.
Cover all three with the kitchen towel and set aside until it (almost) doubles in size. It typically takes 45 to 60 minutes.
When you reach the thirty-minute mark, preheat your oven to 230°C (450°F).
Once the dough is ready, uncover them and place the tray in the middle of the oven.
After 15 minutes, spray the inside of the oven with water three times, then lower the temperature to 200°C (375°F to 400°F).
Keep the tray of semolina bread inside for another 25 minutes.
Transfer them on a cooling rack, then serve once it has properly cooled.
