Fresh fish actually does not smell fishy. When it is still a maximum of 2 days after being caught, fish tend to be odorless or have a sweet aroma. . However, if you’ve kept your fish in the freezer for a few days and it starts to smell fishy, that doesn’t mean you should throw it away. As long as the fish flesh is still quite dense and chewy, and the skin still looks bright and not slimy, you can still use the fish.
If the fish you are using is a whole fish, clean the fish thoroughly, especially the black part that usually appears on top of the fish after the head is cut off. This part usually makes fish smell fishy.
Clean the fish scales thoroughly, then coat the fish with vinegar. The amount of vinegar used is 2 teaspoons of vinegar for every 1 kilogram of fish. Once coated with vinegar, let the fish sit for about 15-20 minutes.
