If you’re worried about authenticity, probably compare notes with native cooks, but more importantly, check to see if the ingredients are correct. Very easy to get bastardised ingredients; as an example, living in an Asian country, I used to have a hell of a time getting the right herbs and vegetables for doing certain Western dishes with, and very common to get some pre-packaged “mix” of herbs instead.

Japanese food is the dogs bollocks and I have no idea why.

I’m not even hugely keen on fish. But fuck those guys on that crazy little island make some good tucker.
