To use purple corn and give the water its intense color, you should take the kernels out of the cob first. But don´t you dare discard the cobs, because that is where the secret lies: they render even more color than the kernels! Break the cobs or leave them in one piece, add spices, (cinnamon, cloves, allspice), and boil until the water has a deep color. Cool and strain, discarding the solids.
You can also use this water to cook a delicious and unique purple rice, not only colorful, but also full of the diuretic and blood pressure regulating qualities of this exotic ingredient.
