If Phu Quoc Prison, also called the Coconut Tree Prison, is on your tour itinerary, you can just cross Nguyễn Văn Cừ street and take a look at the Phung Hung fish sauce factory on Phu Quoc Island.
Visiting a traditional fish sauce factory on Phu Quoc Island is an interesting experience for the eye and the nose. The Phung Hung fish sauce factory is just a step away from Phu Quoc Prison, and they have a souvenir shop that sells dried fish and other interesting morsels.
Fish sauce, or nước mắm, as it is called in Vietnamese, is a key ingredient in Vietnamese cuisine. The smell of fermenting anchovies might not be appealing to every visitor, but the finished product is savory, salty and aromatic.
Usually it is used as dipping sauce, made from fish sauce, lime juice, sugar, chili and water, to dip the Vietnamese classics in: fresh spring rolls, fried spring rolls, chicken or pork, fish and vegetables, as well as the rolled pancakes banh xeo and banh kot. It is also used to create savory, pickled onions and papaya stripes, traditionally eaten together with the famous sticky rice cakes gifted for Tet holiday.
We actually visited this fish sauce factory on our trip to Phu Quoc Prison, as well as Khai Hoan factory in Duong Dong.
