When we caught a lot of horse mackerel at the pay-by-the-hour fishing pond at the park, the pond's supervisor taught me this technique. If you clean the fish right after you catch them, you can cook them right away when you get home. We put the cleaned fish into a cooler filled with ice and and then take them home. I use this method every time we go fishing.

The picture shows a 15 cm horse mackerel but you can practice with 10 cm ones. Start by piercing all of the fish with the scissors. This way, you can clean large amounts of fish in no time. This time I cleaned a lot in less than 10 minutes. For small horse mackerel, use small fishing line scissors. Recipe by fukaori
