Taking the cooking outside the Kitchen

So our friend, Seth, recently told me that Hillel was making challah and people are able to come and roll the challah dough.  Here are the ingredients of how to make challah:

Ingredients:

1. Dissolve 2 packages yeast, and let sit for 10 min.
2. In a separate bowl, mix 2 eggs with 1/2 cup sugar. Mix in 1/2 cup oil.
3. Add yeast to egg mixture. Add up to 1 Tbsp. salt to mixture. 
4. Alternate 8 cups flour and 2 cups warm water into mixture.
5. Knead.
6. Place in oiled bowl (oil all sides of dough) and cover with a towel - place in warm oven (150 degrees Fahrenheit for 1 minute then turn off) until dough has doubled (approximately 1 1/2 hour).
7. Punch dough down - let sit for 15 minutes.
8. Remove a piece of the dough for the "challah" (see note below).
9. If desired, raisins can be added to the dough at this point.
10. Separate the dough into 4 batches. Separate each batch into 3 strips and braid.
11. Place on lightly greased cookie sheets, loaf pans, or pie pans.
12. Let the dough raise a second time in oven (150 degree Fahrenheit for 1 minute and then off) for 45 minutes
13. Preheat oven 325 degree 
14. Bake 30 to 40 min. until bread is golden brown
