Hoe-guksu (Raw Fish Cold Noodles)

Hoe-guksu lives or dies by chew and sharpness. The noodles must fight back under the teeth, and the raw fish must be clean, cold, and cut thin enough to season all the way through. If either one is lazy, the bowl turns heavy.

My teacher made me rinse naengmyeon noodles until my fingers ached. I thought she was being severe. She was, but she was also right. Starch noodles keep a slippery coat unless you rub them under cold water, and that coat steals the sauce. Rinse until the noodles feel firm and squeaky, then drain them hard. That is the difference between a bowl that tosses cleanly and one that clumps like wet thread.

Traditionally this bowl belongs to Hamhung and the northern coast, where raw skate or flatfish met sweet-potato starch noodles and a fierce cho-gochujang (vinegared chili sauce). At home tonight, buy only fish you would eat raw without apology. If good skate is not in your market, use sashimi-grade fluke, halibut, or sea bream and write down what you used. Memory is a borrowed bowl.
