I was never successful with sourdough bread, yet. With bread started with beer yeast yes. But those breads I can find in the bakeries around here, of every sort, shape and taste, the zone is renown for it's bread, must be the water. And I do not eat much bread anyway with my present way of non-eating.
Sourdough bread is an other story. No body sells it here. And there are no wonder yeast to be bought. I will ask my train friend more details. Apparently it takes even few days to have it raising. It will wait till September when I take the train again, if my friend has not been arrested in the mean time. He is an art broker. (Oh look, I thought that I had lost my touch for surreal. I am glad
