Fernandough is The Flour Districts prized sourdough starter. This starter is the exact starter The Flour District uses for all the delicious sourdough treats we make in house. "Fernandough" has an interesting history of two parents starters. One parent has a 30 year history and the other has a history of over 100 years! All sourdough starter purchases come with physical instructions as well as a digital link in the event you misplace the physical instructions.
