Galchi-gui

Hairtail fish with its distinctive silver skin crisped over a grill, a beloved everyday fish dish from Jeju Island.

Galchi-gui features the long, ribbon-like hairtail fish that shimmers with a metallic silver skin as though plated with aluminium, and grilling it until that skin crackles and the white flesh beneath flakes cleanly is one of the simple pleasures of the Korean fish-cooking tradition. Jeju Island is so strongly associated with hairtail that a local saying claims 'Jeju galchi tastes different from anywhere else', and restaurants on the island serve it as a point of regional pride, often alongside dubu-jorim (braised tofu) and mul-kimchi (water kimchi). The fish has a mild, slightly sweet flesh that pairs well with both simple salt-grilling and with a brushing of gochujang-based sauce during cooking. Hairtail fishing has been documented in Korean waters since the Three Kingdoms period, and it appears in royal tribute records from the Joseon era, suggesting its importance as a quality fish throughout Korean history. One distinctive preparation on Jeju is grilling the fish in large cross-cut rounds rather than whole, which increases the surface area of the delicate silver skin that comes into contact with the heat and is considered the best part. Koreans often describe the pleasure of eating galchi-gui as 'sungnyeong mat' — the straightforward, uncomplicatedly good taste of simple cooking done right.
