It is fish!
But that's not the bad part.
They have vats of this sauce that has been fermenting for 200 years. 200!!! & it absolutely stinks. Worse than any food I've ever tried.
& the taste is like rotten fish, I couldn't get the taste out of my mouth for days. No amount of brushing, gargling or spirits would get rid of it.
I wont be trying that again.
