The Fine Cheese Co, Sourdough cracker range is made only from natural ingredients. With sourdough made using our cultivated spelt sour starter from a wild yeast culture. That we slowly temper, ferment and refresh over four days. And bake on trays, just three packs at a time. Gently for no fewer than 30 minutes at 150°. To produce a thin and crisp cracker with a snap. Rustic in character.
