Squeeze all of the air out of the bag and seal tightly. Freeze at once. To use; defrost several hours until dough rises to double its frozen bulk, then proceed... Proceed with the half recipe of dough. Place the dough in a large well oiled bowl. I spray the used KitchenAid Bowl with non-stick and throw the dough back in, spray the top of the dough as well. Cover with plastic wrap, or a moist towel. Let the dough rise in a warm draft free place. Check the rise at 45 minutes, the "perfect place" rises this bread in 45 minutes. Punch dough down. If you are doing this entire recipe, divide the dough in half. Shape each half into a loaf. This also makes a nice round loaf with a crunchy crust..... Pan Loaf making: beginning at one narrow end, tightly roll up the dough to form a loaf. Pinch seam edge into dough to seal. Lightly oil a loaf pan. Meanwhile, place oven rack in the lower third of the oven; preheat to 190ºC . Place each loaf in a prepared 22 cm X 11 cm X 6 cm loaf pan, seam side down. Cover, let it rise in a warm place free from drafts, until doubled in bulk, about 45 minutes . Check the rise at 35 minutes, the "perfect place" rises this bread in the pan, in 35 minutes. This is the place where I make decorative slits into the top of the loaf. In a small bowl, whisk egg white with one tb of water. Brush a little of the egg white mixture over the top of the loaf and sprinkle with 2 tb Oat Bran, or sesame seeds just before placing in the oven. Bake for 35 minutes on a baking stone or 40 minutes in the bread pan. To make the crust even crustier, spray the top of the loaf with water, and liberally spray the inside of the over at 5 minute intervals and/or place a water filled pie pan in the oven on a lower rack than the bread. (boiling water added to the pie pan just before baking makes sure you have steam....) Makes one or two loaves, each about 18, 1 cm slices.
