Rustic Roots Gluten Free Sourdough Starter is a freeze-dried culture made from carefully selected gluten-free grains and pure water. Cultivated to full activity before drying, it retains the strength and complexity needed to produce flavorful, well-textured sourdough. Once revived, it becomes an active starter that supports natural fermentation in gluten-free baking. Ideal for homemade loaves, it offers a reliable way to enjoy traditional sourdough character without gluten.
