A very short ingredients list and a lot of fermentation time leads to this olive sourdough bread: All wheat flour - mainly white and some whole grain - water, salt and olives is all that goes in here. No is yeast added, only wild yeast is doing the work. Because of that it takes about 48 hours start to finish to make it - including making the sourdough from starter. Not exactly the German style bread I usually make, but at least I got the recipe from a German recipe book. ;-)
