Made with Blue Cónico, our Heirloom Blue Corn Masa Harina is a fine-ground nixtamalized corn flour that looks as good as it tastes. Its deep flavor comes from high quality heirloom corn, which is cooked, slow dried and milled to perfection in small batches. Plus, blue corn is naturally rich in anthocyanins, the same antioxidants that make blueberries blue and are connected to a whole host of health benefits.
