Take the tour ×  I bought ginger at the grocery store last week
and kept it, unpeeled, in the fridge. Today I sliced it open and
there is a ring of a blueish colour, instead of the yellow I was
expecting. The ginger still smells like I'd expect (I haven't
tried tasting it).  Would this be safe for use (I was planning
on putting some in a salad dressing), or should I toss it?

down vote accepted  Having just returned from Hawaii, I actually
have a possible answer for you. There is a type of ginger that
you can get there (though it's not all that common, far as I
could tell) that's called blue ginger. It's just like regular
ginger, only it has the blue layer inside as you describe. There
was a guy selling it at a roadside fruit stand when we were
there.  It should be absolutely safe to use.  edit: I found a
link to somebody talking about it. Hawaiian Blue Ginger

often sold as regular ginger
