Sprinkle a little of the remaining flour over a clean kitchen surface. Turn the dough out of the bowl onto the floured surface. Knead until the dough is smooth and elastic, sprinkling with flour if dough is sticky. Pull the dough into 12 equal pieces. Roll 1 piece into a rope about 15 inches long, then shape the rope into a pretzel or letter. Put the pretzel on one of the baking sheets and repeat w/ the remaining pieces of dough. Break the egg into the sm. Bowl. Add 1 tablespoon water and stir together w/ the whisk. Brush the egg wash over each pretzel, using the pastry brush. Sprinkle with coarse salt with your fingers.
