In a large bowl, whisk flour, salt and yeast until well mixed. Pour in warm water and use a wooden spoon to stir until a shaggy dough forms. The mixture will be wet and very sticky to the touch.
Cover bowl tightly with plastic wrap and set aside in a warm place 8 to 18 hours until dough rises, bubbles and flattens on top.
Heat oven to 450°F. Once oven is preheated, place a 6-quart Dutch oven (with cover) in oven 30 minutes before baking.
Punch down dough. Generously flour a sheet of parchment paper; transfer dough to parchment and, with floured hands, quickly shape into a ball. Place dough on parchment paper and sprinkle top lightly with flour. Top with a sheet of plastic wrap and let rest 30 minutes.
Remove Dutch oven from oven. Uncover dough and carefully transfer to Dutch oven, with parchment paper beneath (if bottom of Dutch oven is not coated with enamel, keep parchment paper beneath dough). Cover Dutch oven and return to oven.
Bake bread 45 minutes covered, then another 10 to 15 minutes uncovered until dough is baked through and golden brown on top. Cool slightly before slicing.
Wallace's is a great place to visit even if you're not looking to stock up on gardening supplies. It's beautiful inside and out, with some space dedicated to inside decor and jewelry, and tons more to the beautification of your patio, lawn, and garden. I went there on a mission to find my mom a succulent and a tiger lily for Mother's Day and we were all thrilled with the results, so much so that I returned make an identical purchase for my grandmother!
