The term “sourdough” has been used to refer to people from the Yukon territory in northwest Canada, particularly those who lived or worked in the region during the Klondike Gold Rush of the late 19th century. The term is thought to have originated from the fact that sourdough bread was a staple food of the miners and other people who lived in the Yukon during this time.
Sourdough bread was a convenient and nourishing food for the miners, as it was easy to transport and could be made with minimal ingredients, including flour, water, and salt. The bread was made using a sourdough starter, which is a mixture of flour and water that has been allowed to ferment over time. The sourdough starter was used in place of commercial yeast to leaven the bread, and the process of making sourdough bread typically took longer than traditional bread-making methods because the dough needed to rise for longer periods of time.
The term “sourdough” eventually came to be used as a nickname for people who lived or worked in the Yukon, and it is still used today to refer to people from the region. The term is often used with pride and is seen as a symbol of the hardy and resourceful spirit of the people of the Yukon.
