To start, mix together 900 grams white bread flour 100 grams rye flour 200 grams 5 seed mix

Next, mix in 300 grams active and bubbly starter 750 grams water

Autolyse (allow to rest) 60 minutes, then add  20 grams salt Mix in by driving the salt into the dough with fingers until well blended Do 4 stretch-and-folds 30 minutes apart (pulling the sides over the middle and turning)

Bulk rise, covered for 60 minutes Set covered in the fridge for 12-14 hours to do the long cold rise Remove from fridge and allow to warm for 60 minutes

Divide dough into two equal pieces Shape into balls and tighten dough surface by tucking and pulling to create tension Bench rest 45 minutes *you can roll each of the dough balls in more seeds/grains if desired*

Set each rolled dough ball into a floured batteton Set the bannetons in plastic bags and rise in fridge 2 to 4 hours Roughly 30 minutes before removing from fridge Set empty cold dutch oven into middle rack of oven Preheat oven to 500 degrees F. for 60 minutes

Remove one banneton from fridge invert dough onto parchment paper Score the dough deeply to achieve the best rise Pick up the dough in parchment paper and drop it into the preheated dutch oven Reduce heat to 450 degrees F. Bake covered for 20 minutes

Remove lid and bake uncovered for 20 minutes or until internal dough temperature reacts 206 degrees F Remove form heat and invert loaf onto cooling rack Repeat bake with the second loaf
