Peel and julienne ginger and spring onion. Soak the spring onion in ice water and reserve for later use.
Clean fish and pat dry. Cut the fillet in half, then score the thick end slightly.
Marinate the fish with the seasoning.
Wash rice and quinoa, and add water.
Bring rice to a boil over medium heat, then reduce heat to low and cook for 8 minutes with the lid on, or until the water is just invisible but the rice is still damp.
Add fish and ginger on top of the rice. Cover the pot again and steam on low heat for another 8-10 minutes until the fish is just cooked.
Meanwhile, heat the oil in a small saucepan until it begins to smoke.
Mix the sauce and pour it over the fish. Turn the heat to high and cook again until light smoke appears and you hear the rice sizzle at the bottom. (about 3minutes)
Add spring onions and ginger on top of the fish, then pour hot oil over them.
Reduce the heat again and cook for another 2 minutes, and the rice should be crispy on the bottom.
Serve hot and enjoy this delightful dish.
