Tender and Delicious Even When Cold!

When scaling the recipe, the ratios of some ingredients may require slight adjustments. Adjust as necessary and season to taste.
- 3 black cod fillets (gin dara)
- 1 tsp sugar
- 3 pinches of salt
- A1 tbsp white miso (rice miso)
- A1 tbsp mirin (sweet rice wine)
- A1 tsp sugar (or more to taste)
- A1 tsp white sesame seeds
- 4 to 5 inches of a Japanese long green onion
- yuzu zest (to taste)
INSTRUCTIONS
Preparation
Sprinkle the black cod with sugar and lay it on a tray. Refrigerate for 1 hour or longer to remove the fishy odor and give the finished fish a refined, mellow flavor. This step will also help to prevent the fish from breaking apart while cooking and ensure a fluffy, tender texture. You can also sprinkle on a little salt if preferred.
- 1
Wrap the black cod in a paper towel to absorb the excess moisture.

- 2
Take a pinch of salt (the amount held between the thumb, index, and middle fingers) and sprinkle it on both sides of one of the fillets from a height of about 1 ft., then press it into the fillet with the palm of your hand. Repeat with the remaining fillets.

- 3
Slice the Japanese long green onion thinly on the diagonal. Mix the (A) ingredients (white miso, mirin, sugar, and white sesame seeds) with the long green onion.
Thinly shave the yuzu zest, cut it into fine strips, and soak it in water.
- 4
Spread the miso sauce onto the surface of the black cod.

- 5
Place the fish skin-side up and grill over medium heat for 12–14 minutes. (We used a two-sided fish grill.)

- 6
(Supplement) Photo: After 5 minutes on medium heat, the green onion will start to sear. Flipping the seared green onion with chopsticks will prevent uneven burning.

- 7
Once a nice sear is achieved, remove the fish from the grill. (Black cod is relatively prone to falling apart, so using a spatula is recommended.)

- 8
Squeeze out the moisture thoroughly from the grated yuzu. Garnish the fillets with yuzu zest and serve.

Tips & Notes
・When flipping or removing grilled fish, handle it gently with a spatula to prevent it from breaking apart.
・We used a salty Tsugaru miso. Taste the sauce and adjust the amount of miso accordingly.
ーIf you prefer less sweetness, reduce the sugar to 1 tsp.
ーIf using Saikyō miso (Kyoto white miso), which is sweeter and lower in salt, a good balance can be achieved by increasing the amount of miso and reducing the sugar to 1 tsp.
