Mul-naengmyeon (물냉면, Cold Buckwheat Noodles)

Mul-naengmyeon lives or dies before the noodles boil. It lives in the broth, and in how cold you have the courage to serve it. My teacher, Master Seong-nyeo, made me taste the same broth three times: warm, cold, and nearly slushed. Warm, it seemed too sharp. In the bowl, with noodles and ice, it finally spoke clearly.

This is a Northern noodle that now sits on summer tables all over Korea, especially when heat makes rice feel too heavy. It asks for patience more than difficulty: make the broth ahead, skim the fat, chill the bowls, cut the radish thin, and rinse the noodles harder than you think proper. Starch left on the noodles will cloud the bowl and dull the bite.

Do not load it with sugar or mustard until you cannot taste buckwheat, beef, and dongchimi. Season the broth a little sharper and saltier than drinking broth, because cold mutes flavor. 손맛 is real; I measure it anyway. Write down the vinegar and salt after your first good bowl, because your dongchimi will never be the same twice.
