Take & bake. American Classic: Izzio's Organic Sourdough is made with the finest organic flour available. Based on a traditional recipe the distinct sour flavor comes from allowing the 3-ingredient dough to ferment for almost 3 days, creating layers of deep flavor and a porous, chewy texture that makes this bread a modern classic. Great bread starts with great ingredients, which is why at Izzio Artisan Bakery we source the highest quality organic ingredients for our breads. We use only authentic small batch baking methods and extended natural fermentation, where some loaves take up to 72 hours. The result is an organic loaf of bread that has a unique texture, deep flavor, is easy to digest and always delicious. Long fermentation, easy to digest. Fresh milled flour nutritious & flavorful.
