170 g whole wheat flour
57 g rye flour
7 g flaxseeds
4 g salt
170 g water
142 g water, more for adjustment
6 g instant yeast
227 g bread flour
57 g whole wheat flour
56 g sesame seeds
56 g sunflower seeds, toasted
56 g pumpkin seeds, toasted
5 g salt
19 g honey
6 g sesame seeds, for topping
In the morning, prepare soaker.
In the evening, dissolve instant yeast in lukewarm water. Add to soaker and all other ingredients for final dough. Mix on low speed for 2 min, until all flour is hydrated. Let rest for 5 min.
Knead 2 min. on medium-low speed, adjust with water, if necessary (dough should be very supple and slightly sticky). Continue kneading for 4 min. more, switching to medium-high speed for last 20 sec. Dough should be still slightly sticky.
Transfer dough to lightly floured work surface and stretch and fold 4 times, with 10 min rest after each folding (total time 40 min.). After last folding, place in lightly oiled bowl, cover and refrigerate overnight.
Remove dough from refrigerator and either de-chill for 2 hrs. before shaping, or shape into batard when still cold. Place on parchment lined baking sheet, brush with egg wash and sprinkle with sesame.
Score de-chilled dough at once; and cold dough after 1 1/2 hrs. (when turning on oven). Mist bread with spray oil, cover and let rise to 1 1/2 times its original size (45 - 60 min for de-chilled dough, 2 - 3 hrs for cold dough).
Preheat oven to 425 F, including steam pan. Bake bread 20 min. at 375 F (steaming with 1 cup hot water), rotate 180 degrees and continue baking for another 27 - 30 min. (internal temperature should be at least 200 F).
Cool on a wire rack.
