Have you ever sliced into a knob of ginger to find a faint blue-green ring circling the perimeter? Don't be alarmed — your ginger isn't bad. In fact, there are a few reasons why your ginger might appear blue, and none about them are bad.

Bred for Blue

How blue is your ginger? If it's just a faint ring, you probably have Chinese white ginger on your hands; if you see a fairly distinct blue hue radiating throughout the entire knob, chances are you've got a variety that's been bred for that color. Bubba Baba Ginger is a Hawaiian ginger that's been crossed with a strain of bluish ginger from India. It begins with a yellow-pink tinge and becomes bluer as it matures. And remember, mature ginger delivers the heat!

Attention: Anthocyanins Present

The bluish hint in some ginger is a result of anthocyanins, a type of plant colorant in the flavonoid family that gives fruits like blood orange and vegetables like red cabbage their vibrant hues. Trace amounts of anthocyanins in certain ginger varieties give it a bluish hue.
