The dough should have risen, and the surface should be dotted with bubbles.
For this recipe, I use a cast-iron pot or Dutch oven which is 24 cm (9.5 inches) in width with a 3.8 litre (4 quarts) capacity. (See Kitchen Notes below)
Place a sheet of baking paper onto your work surface.
Dust some flour onto the baking paper.
Scrape the dough from the bowl onto the baking paper.
Sprinkle the dough with some flour.
Gently pat the dough into a rough ball. I like to do an "envelope fold", that is, pull the top and bottom into the centre, and then pull both sides into the centre. But the dough might feel too wet to work with. You are just trying to incorporate a little bit of flour and to knock out some of the air bubbles.
Transfer the baking paper with the dough to a large, clean bowl. For this step, I like to use a bowl which is about the same size as the cast-iron pot or Dutch oven.
Cover the bowl with a clean tea towel.
Let the dough rest for about 2 hours in a warm place, or until it has doubled in size.
