Sourdough rye is a hearty, tangy bread made by fermenting rye flour with a sourdough starter instead of commercial yeast. It typically features rye flour, water, salt, and the starter culture, and is a staple in Northern and Eastern European cuisines. The long fermentation process gives it a distinct flavor and a dense, moist texture.
