Stir the sponge to deflate.
Add flour, semolina flour, salt, and olive oil to the sponge.
Combine using a stand mixer on low speed for 5 minutes or until dough forms a smooth ball. About 7 minutes if you would prefer to knead by hand.
Apply additional olive oil to the ball of dough and place in an oiled bowl.
Cover with the bowl with plastic wrap and let rise until the dough doubles in size. About 1 hour.
Lightly flour a baking sheet with semolina flour.
Place the dough on floured baking sheet, deflate, and begin shaping into an oval by folding the dough over and pinching the seams.
Place the dough seam side down and cover with oiled plastic wrap until the dough doubles in size. About 1 hour.
Preheat oven to 400°
Once dough has risen, make three slices across the top.
Bake for 40 minutes until golden brown. Baking time may vary. Once done the bread should have a hollow sound when tapped on the underside.
Remove from oven, let cool, and enjoy!
