East coast Gangwon province — Sokcho and surrounding coastal towns; ojingeo-sundae is part of the Sokcho street food culture that also features mayonnaise-seasoned squid dishes and dried seafood markets
Ojingeo-sundae (오징어순대) is a specialty of the coastal regions — most notably Sokcho and the Gangwon coast — where whole squid tubes replace the pig intestine casing of standard sundae. The squid tube is cleaned, the tentacles reserved, then stuffed tightly with a mixture of glutinous rice, glass noodles, mung bean sprouts, and sesame-seasoned vegetables before being sewn shut (or toothpick-sealed) and steamed until the squid cooks and the filling sets. When sliced, the cross-section reveals a ring of orange-pink squid casing around the filling — visually dramatic and texturally dual: the chew of the squid against the soft, fragrant filling.
Served sliced in rounds, arranged cut-face-up to show the filling ring. Dipped in cho-ganjang or light doenjang-salt mixture. Often sold as street food at Sokcho market, sliced to order.
{"Fill the squid tube to 80% capacity only — the filling expands during steaming and an overfilled tube splits at the seal","Partially cook the glutinous rice before stuffing (soak and steam for 15 minutes to par-cook) — raw rice won't fully cook inside the sealed squid in the time the squid takes to cook","Seal the open end firmly — sew with thread, or use multiple wooden toothpicks at close intervals","Steam for 20–25 minutes over high heat — the squid must cook through completely while the filling sets"}
A practitioner seasons the glutinous rice filling with sesame oil, ganjang, and perilla leaves before stuffing — the aromatics must be in the filling itself since the squid casing seals them in. After steaming, brush the exterior of the squid with a light coat of sesame oil before slicing — this prevents the surface from drying and adds a finishing sheen. The sliced cross-sections are served with a simple dipping salt or cho-ganjang.
{"Using raw unsoaked glutinous rice — it doesn't cook through inside the sealed squid and remains chalky","Overfilling — the tube splits and the filling escapes into the steaming water","Steaming at low heat — the squid toughens before the filling heats through"}
