Phú Quốc is a unique fish sauce extracted by long time fermentation of anchovies' flesh at a high temperature, in West Vietnam. The fish extract / sauce has a delicate smell without unusual ammonia tones because of long time fermentation in wooden barrels.
It is dark red to brown and tastes rich and complex, intensely sweet and salty, with a distinctive fatty taste and a sweet aftertaste. Once the final product is made, it is then bottled in plastic or glass containers. It can be used in soups and marinades or act as an accompaniment to noodle dishes and spring rolls.
