I've tried various means of trying to make sourdough bread, including the one linked to above and The Sourdough Home, among others. I have had ZERO luck though I get what looks and smells like what it is supposed to and doubles in volume as it's supposed to for thicker starters. The dough made from it just won't rise. I've tried all wheat, all white and various combinations with the same outcome. the next time I give it a shot, within the next few days, will be with a starter recipe from Emeril Lagasse and is a cheater starter using yeast which can be found here.
