Here’s how to make miso black cod – a simple recipe that requires only 5 ingredients! Start by rinsing the black cod with sake to remove any fishy odor, then pat dry with paper towels. Make the marinade by mixing together equal parts white miso paste, sake, and mirin in a medium bowl, then adding 1-3 teaspoons of sugar, depending on your preference. Reserve about ¼ cup of the marinade to use later, then add the fish to the remaining marinade, cover, and let sit in the refrigerator for a few hour
