Ibaraki Prefecture — Kashima Sea anglerfish fishing tradition; Nakaminato and Hitachi port culture; winter seasonal preparation documented Edo period
Anko nabe — anglerfish hot pot — is Ibaraki Prefecture's most prized winter delicacy, prepared using the extraordinary liver (ankimo) and all seven body parts of the anglerfish (anko) that are traditionally celebrated as the 'seven tools' (nana dogu): liver, skin, ovaries, stomach, gills, fins, and flesh — each contributing a different texture to the communal pot simmered in a miso-based broth made rich by the fish's own liver dissolved directly into the stock. The traditional preparation technique 'dosaburi' (hanging method) involves suspending the anglerfish by its jaw while the chef butchers it, preventing the delicate liver from being crushed by the fish's weight against a cutting board. The liver is lightly pan-fried separately before being added to the broth — a critical step where the fat renders and the protein sets slightly, creating a stable emulsion that coats the broth in a luxurious, creamy layer. Ibaraki Prefecture's Hitachi and Nakaminato fishing ports along Kashima Sea provide the primary winter supply, with Nakaminato fish market in Hitachinaka serving the freshest anko at dedicated anko hot pot restaurants that open only during the November-February season.
Deeply rich, creamy, and oceanic from the emulsified liver fat in miso broth; the anglerfish flesh is mild and tender in contrast to the intense broth; each component (skin, ovaries, stomach) contributes different textures to a single bowl of extraordinary winter depth
{"Dosaburi hanging technique: suspend by jaw for safe butchery — prevents internal organ damage from body weight","Liver pre-frying in same pot: render liver fat into broth base before adding water — creates the characteristic creamy broth","Miso base: mix hatcho or kome miso into the liver-enriched broth for the characteristic Ibaraki anko nabe flavor","Seven tool utilization: each part added at different timing according to cooking requirement","Winter anglerfish (November-February) has the largest, richest liver — peak production season is non-negotiable","No vegetable dominance: anglerfish nabe lets the fish flavors lead; vegetables are supporting elements"}
{"Nakaminato fish market (Hitachinaka, Ibaraki) in January is the optimal anglerfish hot pot experience — market restaurants serve it","The liver is the most prized ingredient — request extra ankimo portions at restaurants serving anko nabe","After the hot pot: add cooked rice or udon to the remaining broth for an incomparably rich shime finishing course","Ponzu and momiji oroshi (chili daikon) at the table provide the essential acidic relief for the rich liver broth"}
{"Adding liver to cold broth without pre-frying — the fat doesn't emulsify and the broth lacks the characteristic richness","Using summer or spring anglerfish — the liver is dramatically smaller and less fatty outside cold-water winter season","Overcooking the delicate parts (skin, fins) — they cook rapidly and become tough if added with the denser flesh","Using delicate white miso instead of robust miso — the anglerfish liver requires a miso with sufficient character to stand alongside it"}
