In a large bowl, mix all the dry ingredients (flour, yeast and salt).
Add water and mix with a large wooden spoon until the dough doesn't stick to the bowl.
Cover loosely and let rise for 18-19 hours at room temperature.
Set the oven to 450°F and let it preheat.
Pour the dough onto a floured surface and shape it into a ball by folding it into itself 4 times.
Place the dough in a baking pan with seams down, cover loosely and let rest for another 30 minutes.
Put the pan in the oven, covered with lid, and bake for 30-40 minutes.
Remove the lid (watch out for hot steam coming out from the pan), and let bake for another 15-30 minutes, until the bread is golden brown.
Remove from the pan and let rest on a metal rack for about 30 minutes before cutting.
