Directions

1. In a pan oven over high heat, combine the dashi granules, water, sake, mirin, soy sauce, sugar and ginger and bring to a boil. Add the fish to the pan, in a single layer and cover with a crack open.
   
2. Reduce the heat to a simmer and cook for 12 minutes. Transfer the fish to a plate and increase the heat to bring the liquid to a boil. Add the tofu to the pan and cook, turning once, until the liquid reduces slightly and its flavor intensifies, 8 to 10 minutes.
   
3. Return the fish to the pan with green onions and continue cooking, basting constantly with a spoon, for 1 to 2 minutes. Remove from the heat, cover and let the fish sit for 10 to 15 minutes, so the fish absorbs even more flavor from the sauce.
