Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Score the cod fillets with a knife, then place on a baking sheet lined with parchment paper.
  2. Step 2: In a bowl, mix 3 tbsp red miso paste, 2 tbsp mirin, 1 tbsp soy sauce, 1 tsp sugar, and 1 tbsp grated ginger. Brush this glaze evenly over the cod fillets.
  3. Step 3: Roast for 12-15 minutes until the glaze caramelizes and the fish is opaque. Meanwhile, peel and dice daikon radish into 1/2-inch cubes.
  4. Step 4: In a blender, combine daikon cubes, 1/4 cup sake, 1 tbsp vegetable oil, and 2 sliced green onions. Blend until smooth, then season with 1/2 tsp salt and 1/4 tsp pepper.
  5. Step 5: Serve the cod immediately, topped with the daikon puree and a drizzle of remaining glaze.
