Blue is a color, not a flavor, but blue raspberry is most definitely a flavor. It's been enjoyed in many different formats, from slushy ice drinks to licorice straws to cupcake icing to bubble gum balls to shave ice syrup. Of course it's also a staple of creating red, white, and blue concoctions for the 4th of July. You can enjoy the tart and tangy flavor of blue raspberry without turning your tongue blue if you enjoy it in the form of blue raspberry-flavored e-liquids from www.cloudchasers.com. Blue raspberry might be the world's best use of blue food coloring, but you don't need food coloring to vape this sweet and sour e-juice treat.
