I've never heard of kneeding salt into the dough. Usually stuff is kneeded in if it will interfere with the little gluten molecules from hooking themselves end-to-end.Marianne said:Oh, I forgot! I learned that I get a lot better texture if I knead for just a few minutes, cover and let it rest for 20 minutes, then knead again for 8 minutes.
Something about letting the gluten relax (etc etc, can't remember now). It was also suggested to not add the salt until the last kneading (again, I can't remember why, something to do with the gluten again), but for some reason that bugged me. It was just weird kneading salt into the dough. I have to admit, that was the best bread I had ever made.
But tons of kneading!
Some salt is needed as soon as the dough is wet. I understand that there's something about needing counter-ions to help the gluten chains slip past one another. Turns out that there are these other gluten-related molecules that are important for relaxation. But the amount of salt needed to achieve this is pretty small; most of the salt put into bread is for taste.
