Place the dough ingredients in the bread machine pan according to order in manufacturer's instructions. Set the electronic panel to dough setting and select start.
Ninety minutes later, the dough should be done. You can leave the dough in the machine until you are ready to braid it.
Divide into two loaves and braid.
Place braided loaves on a greased cookie sheet. Alternatively, place each braided loaf in a greased, rectangular loaf pan or oval challah pan.
Preheat oven to 350 degrees F.
Crack an egg in a bowl and mix with a fork. Brush egg wash over the loaves. Sprinkle with sesame seeds, poppy seeds or oats.
Bake for about 35 minutes, until the loaves are golden.
