I spent last week in New Orleans (shameless plug: if you haven't been since the storm go...the city is bouncing back) and had the chance to visit the Crescent City Farmers Market. There was a man selling German breads and I bought a loaf of Landbrot. It's outstanding. It's got a very open crumb and a mildly sour taste. I've done a little searching and can't come up with a recipe. Any help? Any one bake a bread like this? Any help is much appreciated.
