Boudin Bakery and San Francisco sourdough starter

Boudin Bakery at Fisherman's Wharf operates a demonstration bakery and museum at this location and traces its founding to 1849. The company maintains a 'mother dough' sourdough starter that it claims links back to its 19th-century origins; that continuity is a documented company assertion. Boudin and its sourdough are widely cited in histories of San Francisco cuisine and are common stops on food and history tours.
