When first starting to bake bread, I asked bakers around the world to share recipes with me. While going through old notes, I found an old email with a formula for a landbrot, a German rye shared with me by Biobäckerei Wagner in Rudertinger Germany.
In his wise words to a budding baker, he wrote, "Sourdough bread is complicated. You need a lot of experience. Anyway good luck!" After multiple second-rate results, I think I might of gotten it right. Finally! Here is my adaption, using just sourdough. Danke, backermeister Wagner!
