I am really irritated I went to a couple of stores to get ginger and for some reason today everyone had old ginger and I knew it would be fibrous and stringy inside by the way it looked. At the last store, I went ahead and bought the older looking ginger because it was less dry looking than the ginger at the previous two stores. So I was irritated already when I got home from the search, but then I cut into the ginger and saw it is not only fibrous (but still usable in texture) but BLUE inside. Google is telling me that this is "Hawaiian blue ginger" or special "Chinese blue ginger" but something makes me doubt that. It seems more likely that air got inside and it is oxidized, or light got inside and it is chlorophyll or something. I have seen rotten ginger and this is definitely not rotten. I tasted it and it seems like sharp ginger, nothing unusual.
What has happened to this ginger to make it blue?
I guess I am still gonna use it. Not sure if this is a when in doubt toss it out moment or what. Any advice?
