Ekura-chan saku-saku cookies -- As part of an ongoing battle against invading swarms of giant jellyfish in local waters, some residents of Fukui prefecture have developed a method for converting the sea creatures into a powdered ingredient used in souvenir cookies.

Sold in boxes of 10, the jellyfish treats, called "Ekura-chan saku-saku cookies," can be purchased at JR Fukui station for 580 yen.

The key ingredient in the Fukui-area cookie maker's recipe is powder made from dried, ground jellyfish, which is produced using a process developed three years ago by students from Obama Fisheries High School. The bitter, salty flavor of the jellyfish is said to nicely complement the cookie's sweetness.

In recent years, swarms of Echizen kurage (Nomura’s jellyfish) have been invading the Sea of Japan each autumn, seriously disrupting fishing operations. The giant jellyfish can grow up to 2 meters wide and weigh up to 200 kilograms (450 lbs) each.
