Gindara — Black Cod and Miso Preparation

Ingredients

• 4 × 180 g black cod (sablefish) fillets, skin on
• For the saikyo marinade
• 200 g saikyo miso (shiro miso), pale Kyoto white miso; do not substitute red or dark miso
• 60 ml mirin, pre-reduced in a small pan until alcohol is driven off, then cooled
• 30 ml sake
• 1 tbsp caster sugar
• To serve
• 120 g tsukemono (Japanese pickled vegetables), to cut the richness

Method

1. 1
   Combine the saikyo miso, pre-reduced mirin, sake, and sugar in a bowl. Mix until the marinade is completely smooth and the sugar fully dissolved. The balance between sweet and salty is the foundation of the dish — taste before proceeding: the marinade should be distinctly sweet, with salt present but not dominant.
2. 2
   Coat the fillets completely in the marinade. Press them into a sealed container, ensuring full contact on all surfaces. Refrigerate for 3–5 days. At 3 days the flavour is deeply integrated; at 5 days the enzymatic action of the miso has transformed the texture of the flesh toward the characteristic silky tenderness. A marinade shorter than 24 hours produces a miso-flavoured rather than miso-transformed fish. The flesh should feel subtly firmer at the surface and the marinade will have drawn a small amount of moisture from the fish.
3. 3
   Remove the fillets from the container. Wipe the marinade carefully and thoroughly from the flesh side with a clean cloth or paper; this is where the dish lives or dies — residual miso on the surface will burn rather than caramelise, producing bitter, acrid char rather than sweet lacquer. A thin layer may be left on the skin side if desired.
4. 4
   Heat the broiler or grill to maximum. Place the fillets flesh-side down under the direct heat. Cook for approximately 3 minutes. The surface is ready when it has developed a deep golden-brown crust of even caramelisation with the visual quality of lacquerwork — no grey patches, no black bitter char.
5. 5
   Turn the fillets skin-side down and cook for a further 2 minutes. The flesh should be barely cooked through to the centre — black cod's exceptional fat content means a slightly underdone interior is correct. Press the thickest point gently: the flesh should yield with almost no resistance, remaining translucent at the very centre. Overcooking destroys the buttery texture that makes the fish the proper vehicle for this preparation.
6. 6
   Serve immediately with tsukemono alongside. The pickled vegetables are not garnish — their acidity and sharpness cut directly against the richness of the fish and the sweetness of the caramelised miso.
