About this dish
Galchi-gui is grilled beltfish, salted and pan-fried until the skin crisps and the flesh cooks through.

Beltfish has a high fat content relative to most white fish, and as the flesh heats, its own oil migrates toward the skin, crisping the exterior without the need for added cooking oil. That same fat keeps the flesh moist well after the fish leaves the heat. Each steak should be cut to around three centimeters thick. Thinner pieces lose their moisture quickly under high heat, while thicker cuts will burn on the outside before the center reaches temperature. The pan needs to be fully preheated before the fish goes in: a cold or lukewarm surface causes the skin to stick and steam rather than sear. When the pan is hot enough, the skin releases cleanly and turns golden through the Maillard reaction. Coarse salt is the only seasoning in the traditional Jeju preparation, and nothing else is added. A squeeze of lemon at the table cuts the richness of the oily fish with clean acidity, lifting the aftertaste. Beltfish caught in the waters around Jeju in spring are considered the finest, with firmer flesh and a richer flavor than fish from other seasons.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Cut 400 g beltfish into pieces about 3 cm thick, then check for stray bones.
Press the surface dry with paper towels so the skin sears cleanly instead of steaming or splattering in the pan.
- 2Season
Sprinkle 1 tsp salt evenly over both sides and let the fish rest for 10 minutes.
Blot away the moisture that appears on the surface so the flesh firms up and the seasoning stays balanced.
- 3Control
Add 1 tbsp cooking oil to a pan and preheat over medium-high heat for about 1 minute.
When the oil shimmers in a thin layer, place the fish skin side down without crowding the pieces.
- 4Control
Keep the pan uncovered and cook for 6-7 minutes without moving the fish.
Wait until the edges turn golden and the skin releases easily from the pan before trying to lift or turn it.
- 5Heat
Slide in a wide spatula and turn the pieces carefully, then cook for another 4-5 minutes.
The fish is done when the flesh turns opaque white and a chopstick enters the center with little resistance.
- 6Finish
Turn off the heat and move the fish to a plate, then serve with half a lemon.
Squeeze the juice on just before eating so the acidity balances the rich fat while the skin stays crisp.
