Ginger turned purple?
I had a root (rhizome) of ginger in my fridge. Frankly not quite sure how long, I usually buy a biggish chunk and cut knobs off it til I use it up/it dries out and gets gross. Tonight I cut a chunk off and the inside was purple-blue-green. The ginger smells fine, is juicy and unmoldy, totally normal looking on the exterior, but I am weirded out by its unnatural interior color.
