if you don't believe that my recipes start on scrappy bits of paper

I believe they start in your head, then get a few trials and adjustments in the kitchen before you commit to paper :)

This recipe is definitely something I want to try, once I master the art of making a sourdough starter. No matter what I do, and how clean and disinfected the jar I try to make it in, it goes moldy after a couple of days. :( We do have problems with black mold in the bathroom, and bad ventilation everywhere so we have to keep windows open even during winter, maybe that's why. The landlord says it'll be fixed this coming autumn...
