Is that the same as fish juice the waitress served us when we were served in a Thai restaurant? She motioned like she was holding a fish up with one hand and squeezing it with the other hand. We turned four shades of green and immediately stopped dipping our egg roll in the "juice". GAK!
Yes.
But, after squeezing the juice from the fish they let it ferment.
Right out of the bottle it smells absolutely horrible.
But used in cooking it goes through some chemical change and really does enhance the flavor.
Strange stuff :)
