It’s proven that the first people to create Fish Sauce in Europe were the Romans. Garum was a kind of liquid condiment made from selected fish innards, blood and salt, left to ferment in vats.

Fishes are mixed with sea salt at a certain ratio, for an example 7:3, meaning 7 kilograms of fish goes with 3 kilograms of salt. The mixture (called chượp) is placed into vats for fermenting. The top layer was pressed by bamboo-net and heavy stones. The time for fermentation is about 12 months, after that the sauce will be extracted and sterilized.
