Now that’s a whole ‘nother kettle a-fish.
I’m sure many of the Thai prepared pastes and sauces have fish sauce in them. It has a prominent location on my spice rack.
I wouldn’t want to be anywhere near where they made it however...probably smells just like a lobster-bait truck.
It was at least 3 orders of magnitude worse, almost to the point of my gagging, until my sense of smell shut down. After which, it wasn't too bad at all. Couldn't smell anything remotely 'fishy' for a month w/o thinking about puking, but what the hell. The effects passed by, somewhat later than sooner (shrug).
And I still love nuoc mam...to cook with.
