I was web browsing last night on how to add more sourdough starter to a bread recipe, and to then make the needed adjustments in the amounts of water/flour for proper hydration. A lot of percentages were given, and how to calculate all of it. I thought I bookmarked a particularly good article, but of course, this morning I can't find it. Guess I didn't bookmark it after all. I don't know if it was here on SMF, or elsewhere. Can someone point me in the right direction, please?
