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