Nattu Kozhambu is a traditional Tamil Nadu fish sauce produced by halophilic microbial fermentation of small fish in sea salt.
Origin: Tamil people (Traditional) — Tamil Nadu, India

The resulting glutamates and other umami compounds give the sauce its characteristic amber clarity and savory depth. The process is driven by proteolysis and controlled by salt concentration and temperature.
