1. Activate the yeast: In a large mixing bowl, combine the warm water, sugar, and yeast. Stir gently and let sit for 5-10 minutes until frothy.

2. Mix the dough: Add the flour and salt to the yeast mixture. Stir until a rough dough forms.

3. Knead the dough: Turn the dough onto a floured surface and knead for 8-10 minutes until smooth and elastic.

4. First rise: Place the dough in a greased bowl, cover with a damp cloth, and let rise for 1-1 1/2 hours until doubled in size.

5. Shape the dough: Punch down the risen dough, shape it into a loaf, and place on a baking sheet dusted with cornmeal.

6. Second rise: Cover and let rise for another 30-45 minutes.

7. Bake the bread: Preheat oven to 450°F. Place a pan of water on the bottom rack. Make slashes on top of the loaf and bake for 25-30 minutes until golden brown and hollow sounding when tapped.

8. Cool and enjoy: Let cool on a wire rack before slicing.
