2/3 cup sugar
1 cup oil
2 Tbsp. Salt
4 eggs, slightly beaten
3 cups warm water

GLAZE
1 egg yolk, beaten

In a small bowl dissolve yeast in 1 cup warm water and set aside. Put white and whole-wheat flours in a large bowl and make a well in the center. Add sugar, oil, salt and eggs.

Add 3 cups warm water and the yeast mixture. Mix and knead until smooth, approximately 5 to 10 minutes. Place in greased bowl and oil the top of the dough lightly. Cover and let rise in a warm place for 2 hours. Punch down, knead again 2 to 3 minutes, oil as before and let rise 1 hour.

Separate challah with a blessing. Divided dough into five pieces, shape each challah and put in greased pan. Cover let rise 1 hour.
