Blue Corn Masa-Harina is gluten free and it not only it makes the most gorgeous blue corn tortillas, but it has a sweeter and nuttier taste than the regular white or yellow masa-harinas. Blue corn is a heritage variety of corn grown in Mexico; It is said to be more nutritious than the white or yellow varieties of corn and like many other blue foods, it is full of antioxidants. When you open the bag, the contents look like a very faint baby blue, almost greyish, but when you add water, the colour comes to life and it darkens a lot while cooking. It is tasty and it looks so utterly gorgeous in tortillas!
