I bought this piece of "butterfish" at my local Vietnamese fishmonger in Melbourne, Australia, and found out through this forum (http://chowhound.chow.com/topics/3060...) and in particular this useful reply (http://chowhound.chow.com/topics/3060...) that this could be one of many different fishes including the very scary sounding Escolar. Does anyone have any ideas what fish this actually is, and especially if this is Escolar? There are 2 of us sharing this 350g piece of fish, and I really don't want to get explosive diarrhoea! Thanks!
P.s. It looks a little odd because its thawing from frozen.
