The chewy crust, soft center, and true sourdough flavor combine to make the Seattle Sourdough Waterfront Sourdough the perfect loaf. In 1950, after years of experimenting, Seattle Sourdough proudly perfected its sourdough starter. The result was a sourdough with such a delicious taste, texture, and aroma that they still use the original mother dough today. Whether you want a sandwich, a grilled cheese, or a nice piece of crunchy toast, this pre-sliced round loaf from Seattle Sourdough can handle it.
