THE FRENCH BREAD

Steps:

• Place the sourdough starter, water, olive oil, salt, sugar, yeast, and flour in that order into the pan of a bread machine, set the machine on the dough cycle, and start the machine.
• After the machine has finished its cycle, turn the dough out onto a floured surface, and knead several times; mix in more flour if the dough is very sticky. Cut the dough in half, and roll each piece of dough out into a rectangle about 8 by 12 inches and 1/2-inch thick. Roll the rectangles into loaves the long way, pinch the seams, and taper and pinch the ends of the loaves.
• Line 2 baking sheets with parchment paper, and sprinkle paper with cornmeal. Place the loaves gently onto the prepared baking sheets, cover loosely with plastic wrap, and let rise in a warm place until doubled, about 30 minutes.
• Place a large baking stone onto the center rack of oven, and place a baking dish onto a lower rack. Preheat oven to 375 degrees F (190 degrees C). Carefully pour boiling water into the baking dish.
• Remove plastic wrap from loaves, and slash several 1/2-inch deep cuts into each loaf with a sharp knife. Whisk egg yolk and milk together in a small bowl until thoroughly mixed, and brush the loaves with the egg yolk mixture.
• Place the loaves into the preheated oven on top of the baking stone, and quickly spray the inside of the oven 4 or 5 times with a water-filled spray bottle. Shut oven door; wait 1 minute, and spray again; repeat twice more, spraying the oven 4 times with water at 1-minute intervals.
• Bake about 15 minutes, and remove the water-filled baking dish. Continue to bake until the bread is browned and the loaves make a hollow sound when thumped, about 15 more minutes. Remove bread to cool on racks.
