This four ingredient bread is simple and easy to make. The hint on sea salt on top is what makes this bread so good!
Add flour, sea salt, and yeast into the bowl of a stand mixer or a bowl if you're making without a mixer.
Stir in water gradually until the dough is just wet enough to stay together in a ball. Cover with a damp dish towel and let sit for a minimum of six hours or longer to a maximum of twelve hours.
Place the cast iron pot and lid into the oven and preheat to 475°.
Dust a clean countertop with flour, pour dough ball onto the floured surface and fold into the center about four times, forming a round ball. Cover with towel again while oven and pan continue to heat up to 475°.
Once oven is up to temperature, take lid off and put dough ball into the very hot cast iron pot. Sprinkle or brush with olive oil and sea salt and replace the lid onto the pot.
Set timer for twenty minutes to bake the bread, then remove lid and bake for another ten minutes or so until golden brown.
Remove bread carefully and let cool on a wire cooking rack.
