What is wheat sour?

Wheat sour, often referred to as sourdough starter, is a mixture of flour and water that has been fermented by naturally occurring wild yeast and bacteria. This fermentation process creates lactic acid, giving the dough its characteristic tangy flavor. It serves as a leavening agent for sourdough bread, providing both rise and distinct taste. Maintaining a wheat sour involves regular feeding with fresh flour and water to keep the cultures active.
