Tsukudani

A dish of tsukudani made from kombu

Tsukudani (佃煮) is small seafood, meat or seaweed that has been simmered in soy sauce and mirin. High osmotic pressure preserves the ingredients. Its name originates from Tsukudajima, the island (in present-day Chūō, Tokyo) where it was first made in the Edo period. Many kinds of tsukudani are sold. Traditionally made tsukudani is preservable and has been favored as a storable side dish in Japanese kitchens since the Edo period.

Tsukudani can be made with kombu or wakame seaweeds. It is usually eaten with steamed rice as a flavoring agent since the flavor is very intense (approximately 1 tbsp for one bowl of rice). Finished tsukudani is served chilled from the refrigerator where it takes on a gelatinous texture.
