Ingredients
  

Black Cod (Sablefish)
  • 4-6 fillets black cod fillets 6-ounce, 1-inch thick, preferably skin-on
Miso Marinade
  • 1/2 cup white miso paste (Shiro Miso)
  • 1/4 cup sake Japanese rice wine
  • 1/4 cup mirin Sweet rice wine
  • 2 tbsp granulated sugar
  • 1 tbsp fresh ginger Finely grated

Equipment

  • Glass Pyrex dish
  • Heavy-duty baking sheet
  • Parchment Paper or Foil
  • Saucepan
  • oven

Method
 

  1. Prepare the Marinade: In a small saucepan, combine the sake and mirin. Bring to a gentle boil over medium-high heat and simmer rapidly for about 5 minutes to reduce and cook off the alcohol. Reduce the heat to low.
  2. Whisk in the Umami: Remove the pan from the heat. Whisk in the white miso paste and sugar until the mixture is completely smooth and the sugar is dissolved. Stir in the grated fresh ginger, if using. Let the marinade cool completely to room temperature.
  3. Prep the Fish: Gently pat the black cod fillets completely dry with paper towels. Place the fish in a shallow, non-reactive glass dish.
  4. Marinating Ritual: Generously coat each piece of cod with the cooled miso marinade, ensuring every surface is covered. Cover the dish tightly with plastic wrap and refrigerate for a minimum of 6 hours, but ideally 2 to 3 days for the most profound flavor.
  5. Ready the Oven: Preheat your oven to 400°F (200°C). Line a heavy-duty baking sheet with parchment paper or foil.
  6. Wipe, Don't Wash: Before cooking, use a paper towel to gently wipe off most of the excess marinade from the fish. Do not rinse the fish.
  7. Bake for Structural Integrity: Place the fish, skin-side down, on the prepared baking sheet. Bake for 10 to 12 minutes, or until the fish is mostly cooked through and flakes easily at the edges.
  8. The Final Glaze: Move the oven rack to the highest position (about 6 inches from the broiler element). Switch the oven to the broiler setting. Broil the black cod for 2 to 3 minutes, watching carefully the entire time, until the glaze is deeply golden brown, caramelized, and just starting to char slightly in spots.
  9. Serve Immediately: Transfer the fish gently using a wide spatula to avoid breaking the delicate flaky flesh. Serve immediately over rice or with fresh vegetables.
