This marinade originally reigns from Chef Nobu. He leaves his on for 3-4 days, but I found that 1-2 still delivered great flavor if you don’t plan that far in advance. While this will look like a lot of marinade, the fish gets a generous bath in it, and then excess wiped off before a quick broil in the oven.

You can find mirin, a subtly sweet rice wine, in the international section of larger grocery stores, or at well stocked Whole Foods or Sprouts. Same goes for miso paste, which you will find in the refrigerated section, likely near the tofu, or other fermented condiments.
