Two 24-ounce loaves of authentic San Francisco sourdough bread from Boudin Bakery, The Original San Francisco Sourdough™. Each loaf is pre-sliced and oval-shaped, baked fresh using the same mother dough starter cultivated since 1849 during the California Gold Rush. This traditional sourdough is made with just four simple ingredients: flour, water, salt, and the unique wild yeast culture (Lactobacillus sanfranciscensis) that thrives in San Francisco's distinct climate.

Boudin Bakery is San Francisco's oldest continuously operating business, founded by Isidore Boudin who combined French baking techniques with the sourdough prevalent among Gold Rush miners. The bakery's legendary mother dough was famously saved by Louise Boudin during the 1906 San Francisco earthquake, preserving the family legacy for generations. Each loaf maintains the signature tangy flavor and chewy texture that has made Boudin sourdough a San Francisco icon for over 175 years.
