Salmon Nanbanzuke (sake no nanbanzuke, 鮭の南蛮漬け) is a type of Nanbanzuke—a traditional Japanese cooking method where fish or meat is fried and then marinated in a sweet vinegar sauce (nanbanzu) seasoned with chili pepper (nanban) and green onion. The name Nanban (“Southern Barbarian”) is said to have roots in the food culture introduced by the Portuguese and Spanish (Nanban people) who came to Japan from the 16th to the 17th century.
In this recipe, tender and nutritious salmon (sake) is marinated in sweet vinegar with plenty of vegetables such as onion, carrot, and green pepper. This cooking method allows the ingredients’ natural umami to merge with the acidic vinegar, resulting in a dish that is refreshing yet deeply flavorful.
