• Yield: 4 fillets
• Dietary Type: Dairy-Free (naturally), Gluten-Free (check miso label)

Ingredients

• 4 cod fish fillets (approximately 6-8 oz each)
• 150 ml mirin
• 450 g white miso
• 225 g granulated sugar
• Sake (quantity not specified, use intuition)
• Pickled ginger, for garnish

Equipment Needed

• Medium saucepan
• Wooden spoon
• Paper towels
• Non-reactive dish or bowl
• Plastic wrap
• Oven
• Grill

Instructions

1. Begin by creating the miso marinade. In a medium saucepan, combine the sake and mirin. The exact amount of sake requires a touch of intuition; start with roughly half the volume of mirin and adjust to your preference – you’re aiming for a slightly sweet, fortified base.
2. Bring the sake and mirin mixture to a boil over high heat. Let it boil for approximately 20 seconds to allow the alcohol to evaporate. This step is crucial for refining the flavors of the marinade.
3. Reduce the heat to low and add the white miso paste. Gently incorporate the miso into the warm liquid using a wooden spoon. Stir continuously until the miso is fully dissolved and the mixture is smooth.
4. Increase the heat back to high and add the granulated sugar to the saucepan. Keep stirring constantly to prevent the sugar from burning and sticking to the bottom of the pan.
5. Continue stirring until the sugar is completely dissolved into the mixture, creating a glossy, viscous glaze. Remove the saucepan from the heat and allow the miso mixture to cool to room temperature. It’s essential that the marinade is not hot when it comes into contact with the fish.
6. While the miso mixture is cooling, prepare the cod fillets. Pat each fillet dry thoroughly with paper towels. This step is important for ensuring the miso marinade adheres evenly to the fish.
7. Once the miso mixture has cooled sufficiently, generously coat each cod fillet with the miso mixture. Ensure the entire surface of each fillet is covered in an even layer of the marinade.
8. Place the marinated cod fillets in a non-reactive dish or bowl. Avoid using metal containers, as they can react with the acids in the marinade, altering the flavor.
9. Tightly cover the dish or bowl with plastic wrap. This will prevent the marinade from drying out and help the flavors penetrate the cod.
10. Allow the cod fillets to steep in the refrigerator for 2-3 days. This extended marination period is what gives Nobu’s Black Cod its signature depth of flavor and melt-in-your-mouth texture.
11. On the day you plan to serve the dish, preheat your oven to 200°C (392°F). Also, preheat your grill.
12. Grill the cod fillets until the surface turns a rich, deep brown color. This step imparts a subtle smoky char that complements the sweetness of the miso.
13. Transfer the grilled cod fillets to the preheated oven and bake for 10-15 minutes, or until the fish is cooked through and flakes easily with a fork. The exact baking time may vary depending on the thickness of your cod fillets, so keep a close eye on them.
14. Once cooked, carefully arrange the cod fillets on individual serving plates.
15. Garnish each plate with a piece of pickled ginger. The tangy, slightly sweet ginger provides a refreshing contrast to the richness of the cod.

Expert Tips & Tricks

• Miso Quality Matters: Use high-quality white miso paste for the best flavor. Different brands will have subtle variations in sweetness and saltiness, so experiment to find your preferred taste.
• Marinating Time is Key: Don’t rush the marinating process. The 2-3 day marination is essential for infusing the cod with the distinctive umami flavor.
• Gentle Handling: Cod is a delicate fish. Handle the fillets gently during the marinating and cooking process to avoid breaking them.
• Prevent Sticking: To prevent the cod from sticking to the grill, lightly oil the grates before grilling. You can also use a grill mat or aluminum foil.
• Internal Temperature: The internal temperature of cooked cod should reach 145°F (63°C). Use a meat thermometer to ensure it’s fully cooked.

Serving & Storage Suggestions

Serve Nobu’s Black Cod with Miso immediately after cooking for the best flavor and texture. It pairs wonderfully with steamed rice and a side of blanched asparagus or bok choy. For a complete Japanese meal, consider serving it with a clear miso soup.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. The flavor may intensify slightly as the miso continues to penetrate the fish. To reheat, gently warm the cod in a low oven (around 150°C / 300°F) or microwave it in short intervals to prevent it from drying out. Freezing is not recommended, as it can affect the texture of the cod.

Variations & Substitutions

• Salmon: As the original recipe suggests, salmon can be substituted for cod. Salmon will yield a richer, oilier dish, but the miso marinade complements its flavor beautifully.
• Chilean Sea Bass: For an even more luxurious experience, try using Chilean sea bass. Its buttery texture and delicate flavor pair exceptionally well with the miso marinade.
• Gluten-Free Miso: If you need a gluten-free version, ensure you use a gluten-free miso paste. Many miso pastes contain barley or other gluten-containing ingredients.
• Sweetener Alternatives: If you want to reduce the sugar content, you can experiment with alternative sweeteners like honey or maple syrup, but be aware that they will alter the flavor profile slightly.
• Spicy Kick: Add a touch of heat by incorporating a small amount of chili flakes or a dash of gochujang (Korean chili paste) to the miso marinade.

FAQs (Frequently Asked Questions)

Q: Can I marinate the cod for longer than 3 days?
A: While 2-3 days is optimal, marinating for slightly longer is generally fine, but the fish might become overly salty. Check the fish after 3 days and determine whether the flavor suits your taste.

Q: What if I don’t have a grill?
A: If you don’t have a grill, you can skip the grilling step and simply bake the marinated cod in the oven. Preheat your oven to 200°C (392°F) and bake for 15-20 minutes, or until cooked through.

Q: Can I use a different type of miso paste?
A: While white miso is traditionally used in this recipe, you can experiment with other types of miso paste, such as red miso or awase miso. However, be aware that they will have a stronger, more pronounced flavor that may overpower the delicate cod.

Q: How can I tell if the cod is cooked through?
A: The easiest way to tell if the cod is cooked through is to insert a fork into the thickest part of the fillet and gently twist. If the fish flakes easily and is opaque throughout, it’s done. You can also use a meat thermometer to ensure the internal temperature reaches 145°F (63°C).

Q: Can I make the miso marinade ahead of time?
A: Yes, you can make the miso marinade ahead of time and store it in an airtight container in the refrigerator for up to a week. Allow it to come to room temperature before using it to marinate the cod.
