About this dish
Gwangeo yuja-ganjang-gui is a Korean grilled flounder dish where fillets are brushed with a glaze of soy sauce, yuzu marmalade, minced garlic, and ginger juice, left to marinate for ten minutes, then cooked in olive oil over medium heat for three minutes per side.

The yuzu marmalade introduces a bright citrus acidity that sits cleanly on top of the soy sauce depth, building a layered flavor profile over the neutral, clean-tasting flesh of the flounder. The two elements do not compete: the soy provides the savory foundation and the yuzu supplies the brightness that keeps the dish from feeling heavy or monotonous. Brushing the remaining glaze over the fish during a final two to three minutes on low heat is what creates the glossy, lacquered sheen on the surface, caramelizing slightly as the sugars in the yuzu marmalade concentrate and reduce against the hot pan. Lemon zest and thinly sliced green onion scattered over the finished fish add a final layer of fragrance that lifts the dish just before serving. Flounder is a delicate fish with thin fillets that break easily if handled carelessly, so flipping the fish only once with a wide spatula in a single, confident motion is the technique that keeps the flesh intact and the presentation clean. The combination of fermented soy and citrus suits the mild white fish without masking its natural flavor.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Season
Pat 380 g flounder fillets dry on both sides with paper towels, then season lightly and evenly with 0.25 teaspoon black pepper.
Removing surface moisture helps the glaze cling and prevents excessive splattering in the pan.
- 2Season
Mix 1.5 tablespoons soy sauce, 1 tablespoon yuja marmalade, 1 teaspoon minced garlic, and 0.5 teaspoon ginger juice until the marmalade loosens. Break up any thick pieces so the glaze brushes on evenly instead of clumping.
- 3Finish
Brush half of the glaze thinly over both sides of the flounder and marinate for only 10 minutes.
Keep the remaining glaze separate for finishing, because the thin flesh can soften if it sits too long.
- 4Control
Heat a pan over medium heat, add 1 tablespoon olive oil, and spread it into a thin coat.
When the oil moves smoothly but is not smoking, lay in the flounder and cook the first side for 3 minutes.
- 5Heat
When the edges turn opaque and the underside is lightly golden, flip the fish once with a wide spatula in one steady motion.
Do not press on the flesh, and cook the second side for another 3 minutes.
- 6Finish
Brush the remaining glaze over the surface, reduce the heat to low, and cook for 2-3 minutes more.
Turn off the heat when the coating looks glossy and slightly reduced, then finish with lemon zest and sliced chives.
