Glass Gem corn, a unique variety of rainbow-colored corn, became an Internet sensation in 2012 when a photo of the sparkling cob was posted to Facebook.
So what does it taste like?
Glass gem corn is a flint corn. The name 'flint' comes from the kernel's hard outer layer so it is not usually eaten like corn on the cob. Most people grind it up into cornmeal and use it in tortillas or grits because it's very starchy. It can also be used to make popcorn (although it doesn't come out rainbow-colored).
