Add all flours, wheat germ in one bowl.
In a second bowl add water (set aside 50g) and levain mix well,
to this add flours and mix just to combine and set aside for autolyse for 30 minutes.
-
In the mean time in a medium bowl combine the flax seeds and hot water and stir to combine.
Once it is cool, then add rest of seeds and set aside.
After autolyse add salt and remaining water and mix well and
set aside for bulk rise for 3 to 4 hours.
Fold every 30 minutes for first 2 ½ hours then after that keep aside for 1 hour intervals. After 1 hour into the bulk rise add the pre soaked seed mixture into the dough and mix well.
Then continue the folding process.
After 3 hours you will feel the dough is aerated and pillowy. If you it not increases in volume give extra hours.
Transfer the dough to lightly floured area and leave rest for about 20 minutes.
If you want to coat the boule with seeds then do that before transferring to banetton. I didn’t do it, cover with dry towel and let it rise for about 3 to 5 hours at room temperature or overnight in refrigerator.
and then into hot Dutch oven .
Score the bread and close the Dutch oven with lid and bake for about 20 minutes, then reduce the temperature to 450F and bake for 10 minutes.
Remove the lid and continue bake for 20-25 minutes until the crust is deep brown.
