National Sourdough Bread Day
April 1, Tuesday
In the United States, sourdough bread became especially popular during the California Gold Rush in the 19th century. Miners and gold prospectors used sourdough to make bread in harsh conditions, since yeast was difficult to obtain. This bread became part of the culinary culture of the western states, especially San Francisco, which is famous for its sourdough bread to this day.
