I found the recipe!
This is obscenely easy to make, delicious, and makes the best french toast the next day. Just go make it. Right now. You have no excuses. Your friends will be impressed that you can, you know, bake! Even if you've never made bread before, this is entirely possible.
Challah (recipe from my Israeli friends Yoav and Hadar, translated from Hebrew)
NOTE: quantities are in grams.
1 kg flour (2.2lb)
25g yeast (yes, that's a lot. short rise.)
170g sugar (6 oz)
1 3/4 to 2 cups water
118 ml oil (4 oz)
1 TBS salt
1 egg, to wash
poppy or sesame seeds, to sprinkle
-Mix flour and yeast together with a fork or whisk.
-Add everything else (except egg for egg wash and sesame/poppy seeds)
-Mix with dough hook for 7-10 minutes until dough is smooth, shiny, and sticks to the bottom of the bowl.
oil (lightly) the top of the dough and cover (I use a towel) for one hour or until doubled.
-Divide dough into two and divide each half into thirds.
-Roll thirds into ropes and braid them (dough should be a bit sticky).
-Put each loaf onto an oiled pyrex 9 x 13 pan and let rise for 1 hour. Loaf should double in size. Brush with beaten egg and sprinkle with seeds.
Bake at 350 for 30-35 min.
This is the just-braided dough.
You can roll/tuck the ends of the braid under for a more polished look.
