I’d have to go with Cod.
Red Cod Yes, but the money is Deep Sea Blue Cod caught off of a boat with a hand-line.
The Blue Cod has nice, meaty fillets and they cook nice and quick.
Just as an aside, did you know that, if you go to a F&C shop these days, unless you specifically ask for Cod or Gurnard or whatever, you will get Elephant fish, it is the default fish (at least down here in Canterbury).
I’m not complaining, Ellies fry up real nice.
