I am enjoying sourdough baking, but ready to start having fun with my favorite recipes. I like using a recipe as a guideline and no want to aadd extra grains, seeds etc, such as millet, quinoa, rolled oats, sesame seeds, sunflower seeds, ground flax, amd have a few questions. How do I know which ones need soaking. Does anyone have a list or good website? Also, since they are not ground as fine as flour can I just add them to the dough or do I need to adjust anything?
