Ingredients

  • 1/2 cup White miso paste
  • 1/4 cup Mirin
  • 1/4 cup Sake (Premium junmai recommended)
  • 2 tbsp Rice vinegar
  • 2 tbsp Brown sugar
  • 4 oz Daikon radish (Cut into very thin sheets)
  • 1 cup Dashi stock

Tools You'll Need

  • Glass or ceramic dish for marinating
  • Paper towels
  • Baking sheet
  • Broiler-safe pan
  • Basting brush
  • Small saucepan

Chef's Tip

A longer marination time of 24-48 hours can help the miso flavor develop throughout the fish. When removing excess marinade before cooking, gently wiping rather than rinsing can help preserve more of the flavor.

Instructions

  1. Make marinade: Whisk miso, mirin, sake, vinegar, and sugar until smooth.
  2. Prepare fish: Pat cod fillets dry, submerge in marinade. Refrigerate 24-48 hours.
  3. Prep before cooking: Remove fish from marinade, gently wipe excess. Rest 30 minutes.
  4. Reduce dashi: Simmer stock until reduced by half, keep warm.
  5. Heat broiler: Position rack 6 inches from heat.
  6. Cook fish: Broil 8-10 minutes until caramelized and cooked through.
  7. Glaze: Brush with reduced dashi before serving.

Plating

Place cod on warmed plate, brush with dashi glaze. Arrange daikon sheets alongside, garnish with micro herbs.

Storage & Reheating

The fish can be marinated for up to 3 days before cooking. Once cooked, leftovers can be refrigerated for up to 2 days. Reheat gently in a 300°F oven covered with foil until just warmed through to avoid overcooking.
