A plastic or metal bench scraper is a helpful tool when shaping and working with this wetter dough.
As an alternative method, replace the sheet of parchment paper in step 4 with a sheet of foil. Generously dust foil with 2 tablespoons (18 grams) cornmeal and all-purpose flour; place shaped dough round, seam side down, on top. After dough rests for 1 hour, flour and score dough as directed. Using excess foil as handles, lower dough into preheated Dutch oven; using a heatproof spatula, center dough and press foil against sides of Dutch oven. Trim foil flush with top edges of Dutch oven, if needed; cover and bake dough as directed. Carefully remove foil immediately after baking. Finished bread may have a slightly different shape, but dough will be much easier to move in and out of Dutch oven.
