Fish sauce really is a gift of the gods and it saddens me that this pinnacle of flavour is nearly lost in the western world.

It has no flavor that I can particularly detect at the end of the process. The smell when you open the bottle is overwhelming, and terrible. I wouldn't venture to sample it directly.
It’s why I now mostly avoid Thai food as a whole, the fish sauce is nauseating and overpowering.
I'm making a pork recipe tomorrow that uses it.
