@Pepper fair call! I certainly wasn't claiming to have invented bread or anything - just sharing a simplified version of a recipe I found here: http://thestonesoup.com/blog/2010/10/rustic-sourdough-the-secret-to-making-amazing-bread-at-home-5-ingredients-simple-baking/ anyway, nice to learn who Jim Lahey is and to know I'm part of a longer tradition than I realised :)
@selenana making this recipe with whole wheat flour works great, it may require a bit longer in the oven though. I've also tried putting in seeds, olives, rosemary, etc... BREAD. yum.
