In a big bowl mix together flour, salt and yeast. Add water to the bowl and using a rubber spatula mix it until it is all incorporated. Cover the bowl with plastic wrap and sit on your counter for 12 to 18 hours.

When ready to bake, preheat oven and your cast iron dutch oven to 450 F degrees. (your dutch oven needs to have a lid, preheat along with the oven)

Flour your work surface and your hands really well. With your floured hands gently remove the dough from the bowl and shape it into a ball.

Remove pot from oven when preheated, and remove the lid.

Take the ball of dough and drop it into the pot. Cover the pot with the lid and place it back in the oven.

Bake for 30 minutes with the lid on, then remove the lid and bake for another 15 to 20 minutes or until golden brown.

Remove from the oven and let cool.

Slice and enjoy!
