Made from the skins of Rubel and Jersey blueberries, this intensely purple powder is jam-packed with antioxidants, fiber and other good-for-you-goodness. Where to start? Well, apart from the obvious smoothie booster, you can use it as an all-natural rub, food coloring (purple bundt cake anyone?) or dusting for a little pizazz on sweet and savory dishes alike.
