Akita Sandfish Hot Pot (しょっつる鍋, Shottsuru Nabe)

Hatahata comes to Akita with winter, small silver fish riding the cold Sea of Japan into the bays, often carrying the beadlike roe called buriko. This pot is built for that moment. If the fish is glistening fresh and the shottsuru is good, you don't need cleverness. You need a clear stock and a light hand.

Fish sauce makes some careful cooks stiffen. They expect a hard smell taking over the room, and shottsuru can do that if you pour it like soy. We don't. In this nabe it seasons the dashi, salt-deep and clean, while tofu and napa cabbage soften the brine and carry it to the spoon.

The detail that decides it is the simmer. Hatahata is tender, and a hard boil breaks it apart, clouds the broth, and sends the roe wandering around the pot like it has lost its manners. Lay the fish in after the vegetables are nearly tender, keep the surface just moving, and serve as soon as the flesh turns opaque. At the winter table this is the main pot, rice nearby, everyone taking from the donabe without fuss. Honmono, but not severe.
