Japanese Ankimo Monkfish Liver and the Culture of Luxury Offal

Ingredients

• 400 g fresh monkfish liver, purchased within 2 days; not previously frozen
• 200 ml sake, for soaking
• 500 ml lightly salted water, for second soak
• 1 tbsp light soy sauce
• 1 tbsp sake, for seasoning
• 1 tsp sugar
• To serve
• 150 g daikon, peeled, for grating
• 1 small piece dried red chilli, for momiji oroshi
• 60 ml ponzu
• 1 tsp karashi mustard, Japanese hot mustard, prepared

Method

1. 1
   Lay the monkfish liver on a clean board. Using a sharp paring knife, remove all visible blood vessels and the thin outer membrane with careful, deliberate strokes. Work methodically: any blood remnant left in the tissue will cause bitterness and grey patches in the finished cylinder. The liver is clean when the surface is an unbroken pale pink with no dark spots or traceable vessels.
2. 2
   Place the cleaned liver in a bowl and cover with sake. Soak for 30 minutes. Drain, then transfer to a bowl of lightly salted water for a further 30 minutes. Drain again and pat thoroughly dry with kitchen paper. The liver should carry no pooled liquid and the sharp raw aroma should have subsided to a mild, clean sea note.
3. 3
   Combine the light soy, sake, and sugar in a small bowl. Brush or spoon the seasoning evenly over the liver. Lay a sheet of plastic wrap on the board. Place the liver along the near edge and roll it into a uniform cylinder of approximately 4 cm diameter, twisting the ends of the wrap firmly to compress the shape. Overwrap tightly in a double layer of foil. The cylinder should feel firm and hold its shape without flex when pressed lightly.
4. 4
   This is where the dish lives or dies. Set up a steamer with water brought to a temperature of 80–85°C — not a rolling boil, but a steady, gentle steam. Place the foil cylinder in the steamer and cook for 35–45 minutes, maintaining the temperature throughout. At full boiling steam, the fat renders out and the protein curdles to a dry, grainy mass; at the correct temperature, the cylinder sets to a smooth, cohesive interior. At 35 minutes, press the cylinder through the foil: it should be uniformly firm with no soft centre.
5. 5
   Remove the cylinder from the steamer and allow it to cool to room temperature, then refrigerate — still wrapped — for at least 1 hour until fully cold and set. Unwrap and slice to 1–1.5 cm rounds with a clean, sharp knife. The cross-section should be smooth, pale pink to beige, and homogeneous, with no white fat pockets or grey patches.
6. 6
   Prepare the momiji oroshi: grate the daikon finely. Press a chopstick into the centre of the mound to form a well, insert a small piece of dried chilli, and incorporate it into the final grating to distribute red flecks throughout — the 'autumn maple leaf' effect without colouring. Arrange two to three slices of ankimo per portion. Place a small mound of momiji oroshi alongside, a small amount of karashi mustard, and pour ponzu into a dipping dish or pool it at the base. The finished plate should carry a clean oceanic scent with the bright citrus note of the ponzu rising above it.
