Oil the inside of your Dutch Oven. Place the dough into the oiled Dutch Oven. Oil the top of the dough. Cover with plastic wrap once again. Allow to raise 1 1/2 to 3 hours. Gently peel the plastic off when time to bake to avoid deflating the dough.
Using a 8 inch Dutch Oven you will bake with the lid off.
Using a 10 in Dutch Oven you can bake with the lid on or off. If baking with the lid on be sure to coat the lid with oil. The dough will most likely push up to the lid and recreate the lid pattern. It also may actually push the lid up higher, until you get more familiar with this baking technique and perhaps not adding all the dough based on your baking vessel size.
