Multigrain 36 hr cold ferment

This is based on Danni's Peasant Bread...thank you Danni ! I milled my spelt, rye and kamut and ground the flax seed. I sifted out the goodies from the flours. I have never done this before but decided to give it a try. I used two different starters that I have had going for a while. Not sure what they are but one was fed only AYW and the other was fed only durum...but that was before and they were now going be on a " water and goodies" feed :). They loved loved loved it. Tripled in 2 hrs. Boom ! I did an autolyse with just the flour and water for about 2 hrs.
