Directions
Dissolve the yeast and sugar in the 1/4 cup of warm water.
Let stand for 5 minutes.
Combine the flours and salt in a mixing bowl.
Make a well in the center of the flour mixture and add the egg, oil, yeast mixture and remaining 1-1/4 cups of water.
Mix well. Knead the dough on a floured board, adding more whole wheat flour until the dough is smooth and elastic.
Place in an oiled bowl. Cover with a damp towel and let rise until doubled, about 1 hour.
Divide the dough into three parts.
Roll each third into a strip about 15 inches long.
Braid the strips together and place on a lightly-oiled baking sheet.
Brush with the beaten egg. Sprinkle on the poppy seeds.
Cover and let rise until doubled.
Bake in a 375 degrees F. oven for 40 to 45 minutes, or until golden brown.
