Junya Yamasaki's Mastery of Ike Jime Transforms Seafood in Southern California
In the waters off Dana Point, California, the bonito, a ray-finned saltwater fish also known as tiger tuna, is the focus of a unique culinary practice introduced by chef Junya Yamasaki. On a chilly December morning, Yamasaki, the executive chef of Yess, demonstrated his expertise in ike jime, a traditional Japanese method of killing fish that ensures both humane treatment and superior taste. Holding the fish by its gills, he swiftly drove a metal stake into its brain, followed by a technique called shinkei jime, which involves sliding a wire down the spinal cord to halt its nervous system. This method is not only more humane than conventional practices but also prevents the release of stress hormones, resulting in fish that taste better and remain fresh longer.
Yamasaki's commitment to quality seafood has resonated with local fishermen, many of whom he has trained in these techniques. Conner Mitchell, a restaurateur and fisherman, noted the remarkable difference in the fish's texture, describing it as "flexible as tissue paper" compared to the stiffness of fish killed by traditional methods. In Japan, such practices are standard in high-quality restaurants, but they are still gaining traction in the U.S. thanks to Yamasaki's advocacy.
The impact of Yamasaki's work extends beyond individual chefs. He has transformed the local seafood supply chain by encouraging fishermen to adopt these techniques, thereby improving the quality of fish available in restaurants. His influence is evident in the kitchens of prestigious establishments, where chefs now prioritize the humane treatment of seafood.
Yamasaki's journey began in Osaka, where he learned to fish with his father. After moving to Los Angeles, he opened Yess, an izakaya that emphasizes local ingredients. His fishing expeditions often involve foraging for mushrooms and diving for shellfish, reflecting his zero-waste philosophy. He believes in the importance of knowing where food comes from and ensuring it is treated with respect from capture to plate.
The introduction of automated systems, like the Poseidon machine designed by the startup Seremoni, aims to make ike jime techniques more accessible. However, Yamasaki emphasizes the irreplaceable connection between the fisherman and the fish, arguing that the personal touch in the process enhances the overall quality of the seafood.
As Yamasaki continues to influence the culinary landscape in Los Angeles, he remains dedicated to educating others about the importance of humane practices in seafood preparation. His techniques not only elevate the dining experience but also foster a deeper appreciation for the craft of fishing and the quality of the ingredients used in Asian cuisine.
