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