Sourdough Challah with Grape Sourdough Starter

Challah, usually braided and typically eaten on Jewish holidays. The dough is enriched with eggs and oil, while using sugar or honey for some sweetness. The fun and exciting part comes from the braiding the dough. A simple 3-stranded braid would be gorgeous enough as the centerpiece for your dinner table. But a 4, or 6 stranded challah would really impress your guests. You can also coil the long braided loaf into a circle.

Grape Sourdough Starter	Dough
454 g Organic red grapes Rye flour Water	240 g Wild Grape Sourdough Starter 2 Eggs, lightly beaten 1 Egg yolks, lightly beaten 120 ml Water 55 g Honey 50 g Sunflower oil 2 tsp Salt 440 g All-purpose or bread flour 1 Egg white 1 tbsp Water 1 tbsp Oatmeal bran or seeds/nuts

1. Start with the starter. Stem grapes into a medium mixing bowl. Crush with hands and cover with a plastic wrap. Use a fork or wooden toothpick to gently poke some holes along the top and set aside for 3-4 days at room temperature. After 3-4 days there should be bubbles in the grape juice/must, indicating fermentation has begun.
   
2. Measure 240 grams of strained grape juice and pour in a 1-quart glass jar. Stir in 120 grams of rye flour to make a thick, porridge like mixture. Set aside for 24 hours at room temperature.
   
3. Measure 1 cup starter, discard any extra. Add in 110 grams of filtered water and 110 grams of rye flour. Let stand at room temperature for 24 hours.
   
   
   
   
   
   
4. Repeat the following day. Some activity should be noticeable: the mixture should be starting to bubble. Repeat twice more. You will need to discard some of the mixture each day.
   
   
   
   
   
   
   
5. The starter is full of bubbles and ready for use to make bread. If you won't be using the starter for several days, put the jar, with the lid covered loosely, into the refrigerator until you're ready to use it. If you are going to use the starter in the next day or two, just leave it out and feed it every 12 hours or so.
   
6. Prepare the dough by mixing the starter, eggs, egg yolk, honey, oil, water, and the salt. Stir. Add flour 1 cup at a time, mixing thoroughly after each addition. Turn out the dough onto a lightly floured surface. Knead the dough, adding more flour sparingly, until the dough is smooth, satiny, has lost most of it's stickiness, and is fairly firm. Cover and allow it to rise until tripled in volume.
   
   
   
7. Punch down the dough, knead briefly and cut into 4 equal pieces. Divide one piece into 3 equal portions. Form each of them into strands of about 30-cm in length, tapered so the center of each piece is thicker than the ends. You should now have three thick and three thin strands.
   
   
8. Braid the three thick strands into a loaf and set aside. Braid the three smaller strands into a smaller loaf. Lightly indent the top center of the larger loaf down its length. Wet it slightly with water. Put the smaller loaf on top of the indention. Beat egg white with a tablespoon of water. Brush this egg wash all over the loaf and allow them to rise until doubled.
   
9. Preheat oven to 180C/350F. Brush the loaf with the egg wash again and sprinkle the top with oatmeal bran. Place it into the oven, bake about 35 minutes.
