Stage 1: Mixing fish with salt
Fresh fish will be mixed with sea salt in the ratio of 3: 1, ie 3 tons of fish will be mixed with 1 ton of sea salt. The mixture will be put into a container or tank, so called “chượp”. The container is made of wood and reinforced with large “wire” rope made of forest rattan. A thick layer of salt will be covered with fish and squeezed.

Stage 2: Fermentation
Fish will be incubated in these container/tanks from 12 to 15 months, then be pulled and carefully mixed to produce the finished product. The hydrolysis time from fish to fish sauce is about 1 year for traditional methods, depending on the container, weather, type of fish and processing techniques. It will be faster in smaller container, hotter weather and softer meat.
