"....I think i'll stick to the tried and tested varieties of fish ."
Sounds like a good idea. Same goes for that "fugu" fish. If you cut it wrong, you die a horrible death and it costs a fortune besides. Unless the taste is light-years better than anything else you could possibly ever eat, why risk it? Lucky for us, there is a whole ocean full of fish that taste, at the very least, as good as and probably much better than these fish.
