About this dish
Kkotge-gochujang-gui is a Korean spicy grilled crab where halved blue crabs are thoroughly coated in a thick paste of gochujang, gochugaru, soy sauce, oligosaccharide syrup, and garlic, then marinated for fifteen minutes before going onto a medium-heat grill.

The sugar in the syrup and the fermented compounds in the gochujang caramelize over direct flame, forming a glossy, dark-red lacquer on the shell while the crab meat underneath is steam-cooked by the insulating shell, keeping it moist and sweet. Controlled medium heat is essential because the sauce scorches quickly: four minutes shell-side down first, then a flip for five to six more minutes ensures even cooking without burning. When the crab is turned, the sauce drips into the interior cavity and coats the exposed meat directly, intensifying the spice penetration on the flesh side. A final drizzle of sesame oil and a scatter of toasted sesame seeds layer a nutty, smoky fragrance over the lacquered coating.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Season
Scrub 500 g cleaned blue crab well around the shell and leg joints, then cut it in half.
Pat the surfaces dry so the thick sauce can cling instead of sliding off during grilling.
- 2Season
Mix 1.5 tablespoons gochujang with 1 tablespoon each gochugaru, soy sauce, oligosaccharide syrup, and minced garlic.
Stir until the paste looks glossy and thick, with no dry chile powder remaining.
- 3Season
Spread the sauce thoroughly over the cut sides and into the shell openings.
Let the crab marinate for 15 minutes at room temperature so the seasoning reaches the exposed meat without drawing out too much moisture.
- 4Control
Preheat the grill over medium heat, then place the crab shell side down for 4 minutes.
If the sauce darkens too quickly or smells scorched, lower the heat slightly before the sugars burn.
- 5Season
Turn the crab with tongs and brush the remaining sauce onto the cut surfaces.
Grill for 5-6 minutes more, until the meat looks opaque and moist and the glaze is dark red, not blackened.
- 6Finish
Turn off the heat and finish with 1 teaspoon sesame oil and 1 teaspoon sesame seeds.
Serve immediately while hot, spooning or dipping into the sauce collected inside the shell cavities.
