Gwangeo-hoe (Sliced Raw Flatfish)

Gwangeo-hoe lives or dies by the knife and the cold. The fish must stay clean and firm, the board must stay dry, and each slice has to be cut with one long pull instead of sawed into raggedness. I won't tell you this is difficult in the dramatic way. It is quiet work. That is harder for some cooks.

At a Korean raw-fish counter, gwangeo is the dependable king: pale, lean flatfish with a firm chew, less fatty than salmon and less showy than tuna. People gather around it for birthdays, promotions, New Year's visits, and the sort of dinner where someone has bought better fish than usual and everyone knows it. You eat it as hoe (sliced raw fish), not alone on a pedestal, but with perilla, lettuce, sliced garlic, green chili, chojang (gochujang-vinegar sauce), and sometimes ssamjang (soybean-chili dipping paste). The fish still has to taste like itself. The sauces sit beside it, not on top.

My teacher made us dry the board twice before she let us touch the fish. Once before cutting, once again after laying the fillet down. Water softens the surface and steals the clean bite. Buy sashimi-grade gwangeo from a fishmonger you trust, keep it below 4 degrees C the whole way home, and slice it only when the table is ready. 손맛 is real, the hand-taste your grandmother trusted, and I still measure it, so it can be handed on.
