Negitoro from "nakaochi" tuna 中落ちでネギトロ

 Our Japanese grocery store "Maruichi", gets a bluefin tuna for sale once a month (I assume from NY).  The date is not fixed and you have to look it up on their website. Since it often arrives on a Friday and because of my work schedule I shop on a Saturday I usually get there the day after they received the tuna. As a result I have the “pick” of what is left over from the previous day and the types of tuna portions and quality available are a bit unpredictable. Nonetheless, I was able to get some pretty decent tuna sashimi. On one of such expedition, I got a segment of tuna back bone with some meat attached. We had a similar item at "Maguro Ganchi" まぐろがんち in Kanazawa 金沢 some years ago. The dish called "negitoro" ネギトロ is supposedly made from "nakaochi" 中落ち and "sukimi" すきみ tuna meat. Sukimi is the fatty meat just under the skin. I made "negitoro" from this nakaochi tuna.

Using a spoon (or more traditionally using a shell), you can removed most of the meat from the back bone and ribs. As you can guess, this is very reasonably priced but tastes good. Many Japanese Izakaya often serve this nakaochi as a sashimi or Korean style marinaded tuna called "Yukke".

Since this nakaochi was not really fatty, I made my usual pseudo-negitoro with the addition of mayonnaise. 

As usual, we had this with a slice of cucumber wrapped up in small rectangle of nori. We had this with "Otokoyama hiyaoroshi"男山ひやおろし...a perfect match!
