• In a large bowl, mix together the flour, salt, and yeast. Add in the warm water and mix together using your hands or a wooden spoon or spatula. Mix just enough to incorporate the wet and dry ingredients; this will form a shaggy dough. Cover with cling film and allow to prove over night for 12-18 hours.
• Dust a clean, dry surface with flour and turn out the dough. Form the dough into a round ball by pulling the sides up to the top center and pinching them together. Move the ball of dough, pinched side down, onto some parchment paper and cover with a cloth to rest.

Baking

• Preheat oven to 450°F. Place a tray on the bottom of the oven Put the Dutch oven with lid off into the oven on the middle rack and allow it to preheat for 20-30 minutes. Once the Dutch oven has heated, remove it from the oven. Transfer the dough and the parchment paper into the Dutch oven. Dust the top of the dough with a sprinkle of flour, put the lid on the Dutch oven, and put it back in the oven. Pour cold water into the pan at the bottom of the oven.
• Bake with the lid on for 30 minutes. Remove the lid, refill the water pan, and bake for another 10-20 minutes until golden brown.

To Finish

• Remove bread from the Dutch oven and allow to cool for at least half an hour before eating.
