Nakji Bokkeum (Spicy Stir-Fried Octopus)

Nakji has long been eaten along Korea's south and west coasts, where the tidal flats are wide. A 2003 Kyunghyang Shinmun series on regional flavors notes that, when transport was poor, families outside coastal areas bought dead octopus strung on straw rope at five-day markets, sold by the score, and cooked it on skewers or stir-fried. Once live octopus began reaching cities in tanks of seawater, the article says, cooks took up many more dishes.

The version Seoul knows best, spicy and stir-fried at high heat, is relatively recent. A Kyunghyang Shinmun report from January 2003 dates the alley's beginnings to the 1960s: octopus restaurants clustered in Seorin-dong, and office workers from nearby Mugyo-dong were regulars, hence the name "Mugyo-dong octopus." One owner there dated her octopus restaurant to 1965, although the same article gives a different founding year (1972) for the restaurant itself, so the exact dates are loose. In the early 1980s, redevelopment and subway construction pushed many of the shops to Cheongjin-dong. The article lists a menu that had stayed the same for about forty years: nakji-bokkeum, clam soup (jogae-tang), potato stew and scallion pancake. A mild soup alongside the fiery stir-fry is the pairing it describes.

Octopus and chili suit each other: the octopus supplies a clean, slightly sweet chew, and the sauce supplies the burn. The Encyclopedia of Korean Culture lists nakji-bokkeum among the standard ways to cook the animal, alongside live sannakji and use as a filling in gimjang kimchi. For the stir-fry's technique, see bokkeum stir-frying.

• Lean protein: octopus is high in protein and low in fat. USDA lists raw common octopus at about 15 g protein and 1 g fat per 100 g.
• Minerals and B12: the same entry shows iron (5.3 mg per 100 g), selenium (about 45 µg) and a large amount of vitamin B12 (20 µg).
• Traditional vigor food: the Encyclopedia of Korean Culture cites an older text that says nakji restores vitality; that is a traditional view rather than a tested claim.

• Seoul (Mugyo-dong) style: very spicy, cooked in small batches and served with clam soup, as in the Seorin-dong and Cheongjin-dong alley.
• Mud-flat nakji: the 2003 Kyunghyang series says hand-caught Muan mud-flat octopus has a deeper flavor than the rock-dwelling octopus of Yeosu, and that thin-armed young sebal-nakji are caught from late October.
• With cured pork: one alley restaurant in the January 2003 report was popular for a bacon-and-sausage octopus dish.
• With noodles: the July 2003 series names octopus stir-fried with ramen (nakji ramyeon-bokkeum) and octopus with thin somyeon noodles among the many ways cooks combine nakji with other foods.
