Method
- Whisk the miso, sake, mirin, and sugar over low heat until smooth and the sugar dissolves.
- Coat the cod fillets in the cooled miso marinade and refrigerate for at least 2 days.
- Wipe off excess marinade and broil the fillets for 8 minutes until deeply caramelized.
- Plate over rice, drizzle with rice vinegar, and garnish with scallions and pickled ginger.
Cooks notes. Recipes are tested in a US home kitchen. Substitute lemon for lime if you must, but the result will read brighter. Salt to taste -- our quantities skew toward kosher.
