Kaiyo-Style Miso Black Cod
The dish that built Kaiyo's reputation: sablefish cured in sweet saikyo miso until it eats like custard, then broiled until the edges lacquer to mahogany. The restaurant version rests on 72 hours of patience; this one gets you 90 percent of the way in a weekend.

Ingredients
for 4 servings
- 680 gblack cod fillets, skin on — four 170 g center-cut pieces, pin bones removed
or: Chilean sea bass · close match — Nearly as buttery; cure the same 48 hours. This is the swap Kaiyo itself uses when sablefish runs out.
or: salmon fillets, skin on · decent stand-in — A different dish but a good one — the cure works surprisingly well on fatty salmon. Pull at 50°C internal.
- 150 gwhite miso (saikyo if you can find it)
- 120 mlsake
or: dry vermouth · decent stand-in — Slightly more botanical; use a touch less so it does not fight the miso.
or: dry sherry (fino) · decent stand-in — Nuttier than sake but disappears gracefully into the cure.
- 120 mlmirin
- 60 ggranulated sugar
- as neededneutral oil, for the broiler rack
- 2scallions, sliced on a hard biasoptional

Palate consensus
- 8 of 12 cooks who answered said too much salt — but your palate leans the other way, so your compile leaves it alone. Yours, not theirs.
- 3 of 12 cooks who answered said not enough acid — your palate profile is neutral here, so it compiles as written.
Every number here carries its denominator. Patterns below our sample floor are not shown at all — and only the strongest ones are allowed to change your compiled recipe.

Combine the sake and mirin in a small saucepan and bring to a boil over medium-high heat. Let it boil for a full 30 seconds to burn off the raw alcohol — lean in and smell it; the sharp edge should be gone.
5 min - 2cure
Reduce the heat to low and whisk in the sugar until fully dissolved. Do not let it scorch — keep the whisk moving along the bottom of the pan.
3 min - 3cure
Pull the pan off the heat and whisk in the miso a spoonful at a time until completely smooth. Return to the lowest heat for a minute if needed to loosen it, then set aside to cool to room temperature — a warm cure will start cooking the fish.

Pat the fillets bone-dry with paper towels. Slather a layer of cure into a glass dish, nestle in the fish, and coat every surface — top, bottom, sides — like you are frosting it.
5 min - 5cure
Cover and refrigerate for 48 hours. 24 hours works in a pinch; 72 is the full restaurant treatment. The miso is slowly drawing out moisture and seasoning the fish to the center — there is no shortcut for this.

Lift the fillets out and wipe off the excess cure with your fingers or the back of a knife. Do NOT rinse — a thin film of miso left on the surface is what caramelizes under the broiler.

Set an oven rack 10 cm below the broiler element and preheat the broiler on high for a full 10 minutes. Brush a broiler-safe rack or foil-lined sheet with neutral oil.

Broil the fillets skin-side down until the miso blisters and chars in spots, rotating the pan once. The sugars burn fast — stay at the oven door for this.

Drop the oven to 200°C (or move the pan to the lower rack) and finish until the thickest part reads 52°C — the fish should just begin to flake but still look glossy and translucent at the center.

Rest 2 minutes, then plate with the scallions. Serve immediately — the contrast of lacquered crust and custard interior is the whole point.
