01 - Dissolve the yeast and sugar in warm water in a small bowl. Let stand for 5–10 minutes until foamy.
02 - Mix bread flour and salt in a large bowl. Create a well in the center.
03 - Pour the yeast mixture and olive oil into the well. Mix with a wooden spoon until a shaggy dough forms.
04 - Turn onto a lightly floured surface and knead for 8–10 minutes until smooth and elastic.
05 - Place dough in a lightly oiled bowl, cover with a damp towel, and let rise in a warm place until doubled (1–1.5 hours).
06 - Punch down dough and shape into a tight oval or round. Place on a parchment-lined baking sheet dusted with cornmeal.
07 - Cover lightly and let rise for 45 minutes.
08 - Preheat oven to 425°F. Place an empty metal baking pan on the lowest rack.
09 - Slash the top of the loaf with a sharp knife. Pour 1 cup hot water into the empty pan to generate steam.
10 - Bake on the center rack for 30–35 minutes until golden-brown and hollow when tapped.
11 - Cool completely on a wire rack before slicing.
