Interesting! I thought fish sauce was exclusively a Chinese-Vietnamese-Thai-Filippino madness!
It can't go bad because it already has!
Nope, it was very popular in Roman times. Generically called liquamen, the best known Roman-era brand was Garum; that was made by a family (Garus I think) which thrived in and around the Bay of Naples.
Romans called it garam. Apicius' Cookbook uses it in a lot of recipes.The Romans apparently used the for the same purpose southeast Asians do - as an economical, rich source of protein in their diet.
