Start by cooking the rice according to package directions. If you are using a rice cooker, set it to the “brown rice” setting.
1/2 cup rice
Place the cod fillets on a piece of parchment paper. Drizzle with oil and rub the minced ginger all over. Season the fish generously with coarse pepper and the ¼ tsp kosher salt. Let sit at room temp for 15 minutes (or up to 30 minutes). Only start cooking the fish once the rice is ready. Have all your ingredients next to the stove.
10 ounce cod, 1 tsp canola oil, 2 tsp ginger, 1/8 tsp pepper, ¼ tsp salt
Heat a small frying pan over medium heat for about 5-8 minutes. Add the oil, place the fish in the pan (I place it with the top side of the fish down). There is no skin on the fish, but you can tell which side had the skin (face that side up). Sear the fish for 4 minutes. Flip, add the whites of the green onion to the pan and cook the fish on the second side for another 4 minutes.
1 tbsp canola oil, 2 stalks green onion
Add the butter in pieces around the fish (not on the fish), add the chili flakes, sugar and vinegar to the pan. Tip the pan towards you and using a spoon, baste the top of the fish with the liquid in the pan. Do this for about 30 seconds, remove from the heat.
1 tbsp butter, 1 tsp sugar, ¼ tsp red chili flakes, 1 tbsp rice vinegar
Prepare 2 serving plates with a scoop of black rice. Sprinkle the rice with the green parts of the green onion, a piece of cod on part of the rice and spoon the pan juices all over.
Serve immediately.
