Anko Fish Hot Pot Goosefish Winter Tohoku

Ingredients

• 1.2 kg monkfish (anko) — seven tools: liver, stomach, gill, skin, ovaries, cheek meat, fin, plus white flesh, hung and butchered downward from a hook; skin retained
• For the miso broth
• 1.2 L dashi
• 80 g white miso (shiro miso), for lighter version; substitute red miso for assertive winter version
• 60 ml sake
• 300 g negi (Japanese leek), cut into 4 cm lengths; used generously
• 200 g firm tofu, cut into cubes
• 100 g enoki or shimeji mushrooms, trimmed
• For the shime
• 200 g udon noodles, added to remaining enriched broth after all fish is eaten

Method

1. 1
   Hang the monkfish from a hook over a clean work surface. Butcher downward with a heavy knife, removing the seven tools — liver (ankimo), stomach, gill membrane, skin, ovaries, cheek meat, and fin — keeping each separate. Cut white flesh into generous pieces. The skin is retained and cut into broad strips; its gelatin is one of the most prized elements of the dish. The fish is too gelatinous to butcher flat on a board without tearing. The prep is done when all seven parts are separated, clean, and held in individual bowls.
2. 2
   Bring the dashi to a gentle simmer in a donabe or heavy pot set at table. Dissolve the miso in a ladleful of hot dashi, then stir the thinned miso back into the pot. Add sake. The broth is ready when it is uniformly cloudy-gold, faintly salty at the rim, and carries a clean sea-miso aroma — it must not boil hard at any point.
3. 3
   Add the skin, stomach, gill, ovaries, fin, and cheek meat to the simmering broth. These organs require the longest exposure; the skin in particular must have time to release its collagen and become silky and jiggly. Simmer gently for 6–8 minutes. The skin is ready when it has turned translucent and yields with no resistance to gentle pressure from a chopstick.
4. 4
   Add the negi, tofu, and mushrooms. Then lay in the white flesh pieces. White flesh cooks in 3–4 minutes; it is done when it has turned fully opaque and flakes cleanly at the thickest point when pressed with a chopstick — not before. The negi should have softened to sweetness.
5. 5
   This is where the dish lives or dies: add the ankimo (liver) in the final 2–3 minutes only. It is placed on top of the simmering broth, not submerged, and cooked just until its outer surface is set and it has lost its raw grey interior when broken. Extended cooking beyond this point turns the liver grainy, dry, and mealy — the defining richness of anko nabe is destroyed. Serve immediately from the pot into individual bowls; the liver may be briefly pre-steamed and added at service as an alternative.
6. 6
   After all fish and vegetables have been eaten, the broth will have been progressively enriched by the collagen released from skin and organs throughout the meal. Add udon noodles directly to this remaining broth and simmer until tender. This shime (finishing course) is the culmination — the broth should be thick, deeply oceanic, and coat the noodles visibly.
