Footage shows an ancient cooking hack for gutting a fish in a few seconds - using only a pair of chopsticks. <br /><br />The technique, which originated among Japanese housemaids hundreds of years ago, sees the two sticks plunged down the fresh fish's throat.<br /><br />With a quick twist, they tear out the innards then pluck them out - leaving the creature ready to be cooked.<br /><br />Chef Nathakorn Saruthanajarern demonstrated the kitchen hack this week using mackerel at his Japanese restaurant, Kansaku, in Bangkok, Thailand. <br /><br />He said it is important not to damage other parts of the fish when using the chopsticks hack, but amateurs could also do it in their own kitchens.<br /><br />Natthakorn said: ''There aren't many chefs that know about this technique. It comes from Japan. <br /><br />''The cook who taught me said that long before modern equipment, Japanese housemaids would use the chopsticks to remove the insides of the fish.<br /><br />''I think it's a clever method and something that people can use at home, they just have to be careful not to damage the bones or meat.''
