San Francisco Sourdough Starter

Description

Early settlers in the West, especially those adventurers who traveled north to Alaska, relied on sourdough to leaven bread before commercial baking powder and yeast were readily available.
"Sourdough" even became the nickname for California Klondike miners at the turn of the last century because they carried starter in their backpacks to make bread without having to find a town, let alone yeast.
