Kelp, which is an indispensable ingredient in Japanese cooking, plays an important role to bring longevity and good luck to the people who consume it at the beginning of the New Year. Kobumaki is a dish in which hydrated dried herring is wrapped and rolled in a piece of hydrated kelp sheet, and simmered tender. Here is the old post of the dish where you find the recipe. Since dried herring is not available here, I use smoked fish. The smoked fish needs to be soaked overnight to remove much salt. This year I used kanpyo gourd strips to tie the rolled fish and kelp, so everything is edible!
