Getting Rid of Salt from Saltfish Saltfish can be either soaked overnight or boiled to get rid of the excess salt. When boiling saltfish, I usually wash any visible salt from the fish before boiling twice. After rinsing the saltfish, I add cold water and the fish to a small pot and bring to a boil. The fish wills till be a little salty at this point so I repeat the step once more before moving on with the recipe. Whenever I use saltfish for any dish, I seldom use salt as the salt in the fish add flavor to the dish. You may add salt to your liking. This recipe can be vegan with the exclusion of the saltfish.
