I just bought a 25lb sack of Danko Rye berries from Farmer Ground Flour and am excited to experiment! I decided to go with the Rye Sourdough recipe from The Perfect Loaf. I didn't feel like sifting the rye so I mixed up the flours used a bit and did 40% whole grain rye, 30% whole grain spelt, and 30% whole wheat. For the 15% seed soaker I used pumpkin seeds, sunflower seeds, and steel cut oats.
I'm in the process of waiting at least 24 hours to cut into the loaf - fingers crossed.
