In a small bowl, dissolve the yeast and sugar in 100ml lukewarm water. Let it sit for 10 minutes until frothy.
In a large mixing bowl, combine the bread flour and salt. Make a well in the centre and pour the yeast mixture and the remaining water.
Mix the ingredients with a wooden spoon until a shaggy dough forms.
Transfer the dough to a floured surface and knead for about 10 minutes until smooth and elastic.
Place the dough in a lightly oiled bowl, cover it with a damp cloth, and let it rise in a warm place for 1-2 hours or until doubled in size.
Gently deflate the dough and divide it into two equal parts. Shape each into a slipper shape, typical of ciabatta loaves.
Dust a baking tray with cornmeal and place the loaves on it. Cover with a damp cloth and let them rise for another 30-45 minutes.
Preheat the oven to 220°C (430°F). Place a baking dish with water on the bottom rack to create steam.
Dust the top of the loaves with flour and make several diagonal slashes on the surface.
Bake for 25-30 minutes until the loaves are golden brown and sound hollow when tapped on the bottom.
Let the bread cool on a wire rack before slicing.
Active preparation time is around 20 minutes, with additional rise times totalling approximately 2-3 hours.
