The night before, mix dry ingredients together and add water, mix the ingredients until the dough comes together. Cover with plastic wrap and let it sit for 12-20 hours on the counter top.
The next day, the dough should be wet, sticky and bubbly. Generously flour your hands and baking sheet. Take the dough (if it sticks, flour your hands more) and form an oval shape.
Place it on a baking sheet and sprinkle a generous amount of flour on it. Cover it with a towel. Let the dough rise in a warm place for 1-2 hours.
Preheat your oven to 450 °F. You will need to have 2 shelves in your oven. Place 2 cups of hot boiled water on the deep cooking sheet, on a lower level, inside your oven. This will make the bread crispy on the outside. Place the bread on the top level. Remove water from the oven after 10 minutes. Keep on baking the bread for another 30 minutes or until golden crispy brown.
