Make the rice: I follow the directions on the bag for best results. Rinse the sushi rice in a fine mesh sieve until the water runs clear. Transfer to a medium pot and add the water. Let the sushi soak in rice for 30 minutes before cooking it (if you have time). Bring to a boil, lower to a simmer, cover and cook for 18 minutes or until all the water is evaporated.
While the rice cooks, warm the vinegar, sugar, and salt in a small saucepan and stir just until the sugar and salt are dissolved. Stir into the cooked rice. Set aside and keep covered.
Make the spicy mayo by combining mayo, sriracha, and sesame oil in a small bowl until smooth. Set aside.
Preheat the oven to 400 F degrees.
In a medium bowl, break the salmon with a fork. Add shoyu, honey, garlic, 2 Tablespoons spicy mayo made in Step 3, cream cheese, and scallions, and stir until combined. Taste for seasoning and add salt if it needs it.
Flatten the rice into an 8 x 8-inch baking dish or 9-inch round (no need to grease it). Sprinkle evenly with furikake seasoning.
Spread the salmon mixture in an even layer over the rice.
Top the salmon with more furikake. Drizzle the top with sweet sauce and/or spicy mayo (I tend to use more spicy mayo), if desired.
Bake the dish for 10 minutes, then set it under the broiler for 2-3 minutes, until the top has some brown spots.
Top with suggested accompaniments or as you like! It’s fun to take a piece of nori and scoop the rice/salmon mixture in and top with toppings.
