2. Soak the yellow croaker in hot water at 88℃ for 2 seconds, and store it on ice after the surface of the fish turns white. In this way, the preservation time of fish can be extended by about two times.
3. First of all, don't scrape fish scales or wash them with water. Cut the belly of the fish to remove the internal organs, then soak it in cold salt and boiling water for half a day, then dry it, and coat the scales and belly with a layer of edible vegetable oil. After two or three days, the fish was still delicious.
