Properly done bluefish can be insanely good when its grilled or fried.Especially fried!
I used to have Blues Grilled, at my BIL's, and all the other fish was Great, but the Grilled Blues were Lousy. (He knew about the Darker Meat)
His were normally good sized Blues though.
I had some Smoked twice & they were Great.
It's been awhile, as that BIL passed a few years ago.
