I just posted this recipe over at my blog ChewsWise, where I give much longer description. But I thought bakers here would be interested. This recipe makes two large batards or boules.
70 grams stiff starter
80 grams water
60 grams organic white bread flour
60 grams organic spelt flour
Flax Seed Soaker
1/2 cup (85 grams) organic flax seeds
75 grams water to barely cover the seeds
250 grams sourdough
Flax seed soaker
280 organic white bread flour
280 organic spelt flour
400 grams water
14 grams coarse sea salt
1. Mix starter, cover and let sit overnight (8-12 hours) at room temperature of about 75 F degrees. Pour the flax seeds into a separate bowl and just barely cover with water.
2. Combine the starter and water in a bowl and mix it up with a wooden spoon or spatula until combined. Add the flours and using a plastic bench scraper, spoon or mixer with dough hook, mix the dough until all the lumps of flour are gone. This will take about 2 minutes. Cover and let rest for 20 minutes.
3. Add salt and mix on a slow speed, about 4 minutes. Add the flax seed soaker and using your hands or the mixer, continue mixing until the seeds are evenly distributed.
4. Form into a ball and place in a clean, oiled bowl and cover for the first rise. Fold at 50 minute intervals. Total rise is 2.5 hours.
5. Turn the dough out on a lightly floured counter, divide in two and form into rough batards or boules. Let rest for 15 minutes, then finish shaping the loaves.
6. The final rise should take 90 minutes. Or, to build up the flavor of the loaf, cover the loaves then let them sit for 30 minutes before putting them in the refrigerator in a closed plastic bag. (I use Ziploc Big Bags ). Retard the loaves for 8-12 hours,.
7. Turn the oven to 460 F with a baking stone in the middle of the oven and a rimmed sheet pan on the bottom. Preheat for at least one hour.
8. When ready to bake, slash the loaf in a square pattern with a bread knife or blade, then place in the oven on the heated stone. (Batards can be slashed lengthwise). Pour 2/3 cup of water into the sheet pan and close the door. Bake for 30 minutes. Turn down the oven to 420 F and keep baking for another 15 minutes. Check the loaf. It is done when you rasp it on the bottom with your knuckle and it makes a distinct hollow sound. If not yet done, turn down oven to 400 F and keep baking for 10 minutes. Then turn off the oven, open the door slightly and let the loaf sit for another 10 minutes. Repeat with the second loaf.
