Pat the surface of 200 g salmon fillets dry with kitchen paper and rub ½ tsp salt over both sides. Cover and rest at room temperature for 20 minutes (or 5-10 in warm environments).
Preheat the grill or broiler on medium-high. Pat the salmon dry once more, rub 1 tsp sake over the flesh side, then place it on a wire rack with the skin-side facing the heat source.
Grill until the skin is golden and crispy, about 3-4 minutes. Reduce the heat to medium and flip the salmon over. Grill the flesh side for 3-4 minutes or until pale and opaque.
Remove the salmon from the grill and peel off the skin.
Thinly slice the skin, and place the flesh in a container.
Break the flesh into flakes using a spatula, checking closely for bones as you go. Remove bones with chopsticks or tweezers.
Heat 300 ml dashi stock to approximately 80 °C (176 °F) and then add 1 green tea bag. Steep for about 1-2 minutes, longer if you prefer it strong.
Remove the tea bag and stir in 2 tsp Japanese soy sauce (koikuchi shoyu).
Divide 2 ptns cooked Japanese short-grain rice into serving bowls and sprinkle the top with ground sesame seeds.
Heap the salmon flakes and salmon skin on top of the rice, then sprinkle with finely chopped green onions.
Pour the dashi tea over the rice just before serving and sprinkle with kizami nori (shredded nori). Add a small blob of wasabi paste if you like. Enjoy!
Notes
Pour at the table and eat straight away: The rice starts drinking the moment the liquid lands. Once the grains swell, the texture is gone and there is no way back to it. Pour into the bowls at the last second.Brew the tea stronger than you would drink it: A bowl of rice pulls the flavor a long way back. A cup that tastes balanced on its own arrives at the table tasting of almost nothing.The rice has to be hot: Cold rice pulls the heat straight out of the pour and leaves you with a lukewarm bowl. Warm leftover rice through properly before it goes into the bowls.No grill or broiler: Cook the fish with the pan method in my salmon flakes recipe and spoon those over the rice instead. Everything else in the bowl stays exactly the same.
