NOW, LET’S DELVE INTO THE FLAVORFUL WORLD OF VIETNAM’S MOST CHERISHED CONDIMENT!

 

 

 

Nước Mắm (fish sauce) is a quintessential Vietnamese condiment, fermented from anchovies, offering a savory, umami-rich flavor that forms the backbone of countless traditional dishes and dipping sauces.

1. The Traditional Way: Fish, Salt, and Time

 

  The production of nuoc mam is an ancient art passed down through generations. Each year, skilled fishermen go out to catch fresh, tiny anchovies – the primary ingredient that creates the distinctive flavor of fish sauce. Besides anchovies, some other fish like mackerel and scad are also used.

  Immediately after being caught, the fresh fish are thoroughly mixed with a large amount of sea salt, following the secret ratio of each family or facility. The fish and salt are then fermented in specialized containers: from small earthenware jars used by households to massive, centuries-old wooden barrels, modern concrete tanks, or composite vats at large-scale production facilities.

  The fish and salt are layered alternately, with a thick layer of salt on top. Then, bamboo or wooden planks are used to press everything down, ensuring the fish remains submerged in the brine. The salt inhibits harmful bacteria and creates an ideal environment for the natural fermentation process. Under the influence of temperature and pressure, this mixture gradually transforms into premium fish sauce.
