They don't make sourdough bread like they used to — not even in San Francisco! The city used to be renowned for its sourdough bread as far back as the California gold rush of 1849. I call this recipe "sour bread" because it does not use a traditional sourdough culture; it would thus be misleading to call it "sourdough".

Through the years, San Francisco sourdough has been closely studied by microbiologists and food scientists. The microorganisms that produce the acids that give the bread its tangy flavor are well known.
