Galchi-gui (갈치구이, Grilled Hairtail)

At Jeju's autumn fish stalls, the good galchi doesn't need shouting. It lies silver and firm in thick cross-cuts, and the seller knows to ask whether you want it for gui (grilled fish) or jorim (braised fish). For this one, choose gui. Cook the month you're standing in; if you can find autumn hairtail, this is when the fish has enough fat to cook in its own skin.

This dish lives or dies by restraint. Notebook 38 says: 700g fish, 6g salt, no garlic, no soy sauce, no oil. That looks too plain to people who think Korean food must always announce itself in red. It doesn't. Galchi-gui should taste like the fish first, with salt doing only the work salt must do: firming the flesh, pulling out surface moisture, and helping the cut sides brown cleanly.

The cook's work tonight is simple, but not careless. Buy firm fish, clean the blood from the bone line, dry it harder than you think, salt it evenly, and then leave it alone in the pan until it releases. Move it too early and the flesh tears. Add oil and you mute the clean fat of the fish. A plain dish has fewer places to hide lazy hands.

Serve it with rice, kimchi, and one quiet namul. Pick the flesh from the center bone at the table. This is weeknight food, but weeknight food is where a house proves itself.
