Preferment
Four hours prior to mixing the final dough, prepare the preferment by mixing all the ingredients. Final dough temperature should be 77°F. Set aside.
Cracked wheat soaker
Blend cracked wheat and rye meal with hot water. Set aside.
Final dough
Mix all ingredients except the salt and soaker on first speed for about four minutes. Mix on second speed for two to three minutes to develop the dough. Add the soaker and salt, mix on first speed until incorporated. Final dough temperature should be 77°F.
Bulk ferment the dough for two hours with a fold at one hour. Divide the dough into 1-lb. (500-g) pieces; let rest for 20 to 30 minutes. Shape into batards, and place seam-side up on lightly floured canvas. Proof for about one hour.
Score the loaves and bake at 440°F with initial steam for about 20 minutes.
