The most delicious challah bread!

1. Oil a large ceramic or glass bowl and set aside.
2. Mix together yeast, sugar, and warm water, let sit until forms (15 min).
3. Pour yeast mixture into a large Cuisinart or Mixmaster (or mix by hand).
4. Add 2 eggs and 3 cups of flour. While machine is blending, add vanilla, oil, and salt.
5. Add 4 cups of flour (1 cup at a time) until well blended. Turn dough onto a lightly floured surface and knead dough until well formed and smooth. Place dough into oiled bowl and cover with a damp towel.
6. Set aside in a warm place to rise for at least 1+1/2 hours (dough doubles). Prepare a large cookie sheet with parchment paper.
7. Punch down dough and separate into two halves. Lightly flour surface and divide each half into 3 equal pieces. Roll out each one into long pieces, kneading out air bubbles, and then braid; tuck under ends.
8. Place onto prepared baking sheet. Repeat for the next half. Cover and let rise for at least 1-2 hours.
9. Brush with egg and honey (and sprinkle with poppy seeds if using them); bake for 20-25 minutes in a 350°F oven, turning halfway through cooking time.
