Sourdough Starter - Exclusive for Real Bread Week!

A sourdough starter is a live, fermented culture of flour and water that acts as a natural leavening agent for bread, removing the need for commercial yeast. It houses wild yeast and lactic acid bacteria that consume the flour, creating gas to make bread rise and providing a characteristic tangy flavour. 250g. Photo shows 500g.
