In a large bowl, sift together the flour, yeast and salt. Mix well so ingredients combine well
Slowly stir in the warm water, start with about 1 cup, mix and add more about a tablespoon at a time until you've added another 1/2 cup.
Gently stir together until dry ingredients are combined with water. Dough should be wet. If still a bit dry, slowly add remaining 1/2 cup warm water as needed.
Cover bowl tightly with plastic wrap and allow to stand in a warm area (we preheat the oven to 100 degrees F, then turned it off and added the bowl right to the over). Allow to sit for 10-12 hours. Once finished, dough will be flat on top with bubbles on surface
Remove bowl from oven (if that's where it sat) and place a 4-5 quart dutch oven or cast iron pot to the oven, with the lid on. Preheat oven (with the dutch oven inside) to 450 degrees F. Allow dutch over to sit in the oven for 30 minutes.
Sprinkle a piece of parchment paper with a light dusting of flour. Remove dough from bowl and place on parchment paper. Roughly shape dough into a ball, sprinkle a bit of flour on top and loosely cover with plastic wrap. Let dough stand for 30 minutes.
Carefully remove preheated dutch oven (it will be hot) and place parchment paper and dough to the dutch oven. Cover with lid and bake for 35-45 minutes.
Remove lid and allow to bake an additional 8-10 minutes, until surface is golden brown. Remove and allow to cool slightly before serving.
