Proof your yeast (if using active dry) by mixing it with a little water, and the sugar.
Mix the flour, water, proofed yeast, and discard together and allow to autolyze for 15-30 minutes.**Note: if use instant yeast you can add it right to the dough without proofing it. Add the salt perform a series of stretch and folds. Cover with a wet towel and let rest for 15 mintues.
Perform two more sets of stretch and folds 15 minutes apart. After the last stretch and fold you are going to let the dough rest until doubled. About 30 minutes.
While the dough is resting put your dutch oven in a cold oven and preheat to 500℉.
After 30 minutes transfer the dough to a banneton. I like to pinch the top of the dough to give it some tension. Place inside a grocery bag and rest in fridge for 1 hour.
After the hour take the dough out, transfer to a piece of parchment paper and score the top.
Take the dutch oven out of the oven place the dough into the dutch oven, then put the lid on and put it back into the oven.
Lower the oven temperature to 425℉. Bake it for 22 minutes with the lid on, then 12 minutes with the lid off.
Allow to cool for at least one hour before cutting.
