If you need to gut your catch, apparently all you need is a pair of chopsticks. Yes, in the video above you will see a fish’s guts get yanked out of its mouth. If you need that warning after reading the title, well, I don’t know what to say.
This fish cleaning method is known as the “tsubo-nuki” technique in Japan. It’s ideal when you’re serving fish whole. The gutting method, in the video above, removes fish innards and gills without the need to cut the fish open or remove the head. All you have to do is take a pair of chopsticks, insert them into the fish’s mouth past the gills, give the chopsticks a few twists, then slowly pull the innards out through the mouth. From there you simply rinse the inside of the fish with water and prepare as you wish or freeze the fish.
