This lovely meal came from a dear friend of mine named Sumiyo. I met her in my college Ceramics program. On top of being a gorgeous Japanese native, and an AMAZING ceramicist she also was a phenomenal cook. She invited me over to teach me some authentic Japanese cooking. She gave me slippers to wear and a Japanese apron she brought with her to the States. This dish, known as Nanban-zuke has become a treasured favorite of mine. I always think of her when I'm preparing this dish. More or less it was explained to me that Nanban-zuke means a marinading of deep fried food in vinegar. I was taught to use salmon, but I've read about many other things used since the Portuguese and Spanish enjoy this process as well.
