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