Note: If you're using AP flour, use 1 + 1/2 cup warm water instead.
Mix with your hands. The dough should feel "wet" and "sticky" and shouldn't hold it's shape. If it does hold it's shape, you need more water. Add 1 tbsp of warm water at a time until it's sticky a sticky loose blob.
Cover the bowl with saran wrap or a damp dish cloth.
Allow to ferment at room temperature for 12-16 hours.
Proofing the Dough Ball
Take the saran wrap or towel off and put some flour on your hands. Then fold the sides in to form a ball.
Line a baking sheet with some parchment paper and lightly dust the surface with some AP flour.
Put the dough ball onto the paper, seam side down.
Cover the dough with the same bowl you just used to ferment in and allow to proof for 2 hours.
After 1 hour of proofing, preheat your oven to 450F and put your dutch oven in.
Baking the Bread
Remove the bowl from the top of the bread. Trim excess parchment paper and then carefully transfer the parchment paper + dough ball to the dutch oven.
Put the lid on and back on the center rack for 30 minutes.
After 30 minutes take the lid off and bake for 15 minutes uncovered.
After 15 minutes take out of the oven and remove from dutch oven. Place on a wire rack to rest for 1-2 hours.
