1 - In a large bowl, combine 2 cups of Grand Mills All Purpose flour, yeast and salt. Stir in 2 cups of warm water, and beat until well blended using a stand mixer with a dough hook attachment. Using a wooden spoon, stir in as much of the remaining flour as you can.
2 - On a lightly floured surface, knead in enough Grand Mills flour to make a stiff dough that is smooth and elastic. Knead for about 8 to 10 minutes. Shape into a ball. Place dough in a greased bowl, and turn once. Cover and let it rise in a warm place until doubled.
3 - Punch dough down, and divide in half. Turn out onto a lightly floured surface. Cover and let it rest for 10 minutes. Roll each half into large rectangle. Roll up, starting from a long side. Moisten edge with water and seal. Taper ends.
4 - Grease a large baking sheet. Sprinkle with cornmeal. Place loaves, seam side down, on the prepared baking sheet. Lightly beat the egg white with 1 tablespoon of water, and brush on. Cover with a damp cloth. Let it rise until nearly doubled, 35 to 40 minutes.
5 - With a very sharp knife, make 3 or 4 diagonal cuts about 1/4 inch deep across top of each loaf. Bake in a preheated 375 degrees F (190 degrees C) oven for 20 minutes. Brush again with egg white mixture. Bake for an additional 15 to 20 minutes, or until bread tests done. If necessary, cover loosely with foil to prevent over browning. Remove from baking sheet, and cool on a wire rack.
