My gluten free sourdough journey began as one of frustration, of reading recipes that read like "War and Peace" they went for pages and pages, and they never worked! I'd get inspired, get my starter going, prepare and bake two or three loaves, then put my notes away and give up, they were awful. Then one day I pulled out all of my notes, poured over them, making adjustments to the ingredients here and there, and simplifying the whole process. I have now been making gluten free sourdough for a few years, and sharing my recipes and knowledge for almost as long.
The following morning line a tin with baking paper (refer to notes).
Whisk together the psyllium husk, water and molasses and set it aside for 5 to 10 minutes, until it becomes gelatinous.
Transfer the dough to a lightly floured work surface and knead lightly, shaping it to fit into the loaf tin.
Carefully place the dough into the lined loaf tin, cover loosely with plastic wrap, and set aside in a draft free warm place for 3 to 4 hours (if it is warmer you can reduce the time to 2 to 3 hours).
Preheat the oven to 240˚C.
Remove the plastic wrap, lightly dust the top of the loaf with brown rice flour or buckwheat flour, and then, using a razor blade or tip of a sharp knife, score the dough. Place the loaf on the middle rack in the oven and bake for 30 minutes, then reduce the heat to 200˚C and continue to bake for an additional 40 minutes.
Remove the loaf from the oven and after removing it from the tin, place it directly onto a rack and allow to cool completely before cutting.
