Line baking sheets with aluminum foil dull side up, or parchment paper and spray with Pam.
Divide dough - makes 3 to 4 large challah, or 2 to 3 dozen rolls.
Shape or braid them as desired.
Place on prepared pans, cover with plastic wrap and let rise until about triple in bulk about 1 1/2 hours.
Preheat oven to 375°F.
Beat egg and water and carefully paint the surface of the loaves.
Sprinkle with poppy seeds (Can also use sesame seeds or no seeds).
Bake rolls for about 15 minutes, loaves for about 25-30 minutes or until a toothpick inserted into the center comes out clean. If outside has browned but toothpick indicates center not done cover with aluminum foil and continue to bake to retard browning the crust too much.
Cool on a rack.
