Crusty Round Bread

3 cups  all purpose flour
1 3/4 teaspoons salt
1/2 teaspoon yeast
1 1/2 cups water

In a large mixing bowl, whisk together flour, salt and yeast.  Add water and mix until a loose mixture forms.  Cover bowl with plastic wrap and set aside for 12 - 18 hours.  This could go overnight, or up to 20 hours..  Heat oven to 450 degrees.  When the oven has reached temperature place a cast iron pot with a lid in the oven and heat the pot for 30 minutes.  Meanwhile, pour dough onto a heavily floured surface (the dough will be sticky) and shape into a ball.  Cover again plastic wrap and let set in place while the pot is heating.  Remove hot pot from the oven and carefully drop in the dough.  Cover and return to oven for 30 minutes.  After 30 minutes remove the lid and bake an additional 15 minutes.  Remove bread from oven and place on a cooling rack to cool.
