01 - Whisk together bread flour, salt, and instant yeast in a large mixing bowl until thoroughly combined.
02 - Pour lukewarm water into the flour mixture. Stir vigorously with a wooden spoon until a shaggy, sticky dough forms. Resist the urge to add more flour.
03 - Cover bowl tightly with plastic wrap. Let rest at room temperature for 12-18 hours until surface is dotted with bubbles and dough has doubled in size.
04 - Lightly flour work surface. Scrape dough onto surface and, with floured hands, gently fold edges toward center to form a round ball.
05 - Place dough seam side down on parchment paper dusted with flour or cornmeal. Cover with towel and rest 30-60 minutes until puffy.
06 - Position Dutch oven with lid in oven. Preheat to 450°F for at least 30 minutes to ensure thorough heating.
07 - Carefully remove hot Dutch oven. Lift dough by parchment paper and lower into pot. Cover immediately with lid.
08 - Bake covered for 30 minutes to create steam and develop oven spring.
09 - Remove lid and continue baking 12-15 minutes until deeply golden brown and crust sounds hollow when tapped.
10 - Transfer loaf to wire rack. Cool completely before slicing to prevent gummy interior.
