In a large bowl add flour, salt, yeast, and water. Mix until all ingredients are incorporated. (The dough will still be wet.)
Cover and allow to rise in a warm area for 16-24 hours.
When ready, use a spatula to fold the dough over a few times inside of the bowl.
Fold the dough out onto a floured surface and use your hands to divide the dough into two equal-sized pieces.
Line two baking sheets with parchment paper and sprinkle each with 1 tablespoon of cornmeal. Lift the dough halves onto the lined baking sheets. Shape each dough into a rectangle (approximately 8×4-inches).
Sprinkle a little flour over the loaves and loosely cover them with plastic wrap. Let the dough rise again (about 1 hour).
When ready, preheat the oven to 425°F.
Bake the loaves for 22-25 minutes. The bread is done when the bread sounds hollow when tapped. Let cool completely before cutting and serving.
