Sourdough bread is a perfect homesteaders bread because it does not rely on commercial yeast. Instead, it is made by the fermentation of dough using naturally occurring lactobacilli and wild yeast. It has been made since at least 3700 BCE (Gaenzle, 2014).
This means that you don’t have to rely on purchasing your yeast from a store and, better than that, starting a sourdough culture is actually very easy, especially for those in damp climates in the Northwest but sourdough is made all over the world in many different forms.
