01 - Dissolve the yeast and sugar in warm water in a small bowl. Let stand for 5–10 minutes until the mixture becomes foamy, indicating the yeast is active.
02 - In a large mixing bowl, whisk together bread flour and salt. Create a well in the center of the flour mixture.
03 - Pour the foamy yeast mixture and olive oil into the well. Stir with a wooden spoon until a shaggy, sticky dough forms.
04 - Turn the dough onto a lightly floured surface. Knead by hand for 8–10 minutes, pushing the dough away with the heel of your hand and folding it back, until smooth and elastic.
05 - Place the dough in a lightly oiled bowl, turning to coat all sides. Cover with a damp towel or plastic wrap. Let rise in a warm, draft-free area until doubled in size, approximately 1 to 1.5 hours.
06 - Punch down the risen dough to release air. Shape into a tight oval or round loaf by tucking the edges underneath. Place on a parchment-lined baking sheet dusted with cornmeal.
07 - Cover the loaf lightly with a towel and let rise for 45 minutes until puffy and nearly doubled.
08 - Preheat the oven to 425°F. Position an empty metal baking pan on the lowest oven rack to create steam during baking.
09 - Use a sharp knife to make a ¼-inch deep slash along the top of the loaf. Pour 1 cup of hot water into the empty pan on the bottom rack. Immediately place the bread on the center rack and bake for 30–35 minutes until deep golden-brown and hollow when tapped on the bottom.
10 - Transfer the bread to a wire rack and cool completely before slicing to prevent the interior from becoming gummy.
