Muk-naengguk (Cold Acorn Jelly Soup)

Muk-naengguk belongs to the hot months, when the market sells blocks of dotori-muk (acorn jelly) that tremble if the vendor taps the tray. Buy one that was made that morning if you can. Old muk goes stiff at the corners and loses the clean, nutty taste that makes this simple bowl worth eating.

The mistake is cutting the jelly too thin. Thin strips look tidy for one minute, then break apart and cloud the broth. Slice the muk thick enough to lift with a spoon, about 1/2 inch, and keep the broth cold enough that the jelly stays firm. This dish lives or dies by restraint: a clean anchovy-kelp broth, a measured spoon of soy sauce, a little vinegar, enough kimchi brine to wake it up, not enough to turn the bowl into kimchi soup.

My teacher served this on afternoons when no one wanted rice but everyone still needed feeding. She would say, with that face of hers, that a cold dish has no fire to hide behind. She was right. Chill the broth hard, taste it sharper than seems polite, and assemble only when the table is ready. 손맛 is real; I measure it anyway, so the next bowl does not depend on your mood.
