Prepare the Sushi Rice: Begin by rinsing the sushi rice under cold running water until the water appears clear. In a medium-sized pot, combine the rinsed rice with the water and bring it to a boil over medium-high heat. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 15 minutes. After 15 minutes, remove from heat and keep covered for an additional 10 minutes.
Season the Rice: In a small mixing bowl, whisk together rice vinegar, sugar, and salt until dissolved. Once the rice has finished resting, fluff it gently with a fork and fold in the vinegar mixture until evenly coated. Allow to cool slightly at room temperature.
Prepare the Salmon Mixture: In a separate bowl, combine diced salmon with mayonnaise and Sriracha. Stir gently until all pieces are coated. Adjust Sriracha based on desired spiciness.
Layer the Bake: Preheat the oven to 375°F (190°C). In a medium baking dish, spread an even layer of seasoned sushi rice at the bottom. Smooth it out with a spatula. Evenly distribute the spicy salmon mixture over the rice.
Add Toppings: Sprinkle diced avocado, chopped green onions, and sesame seeds over the salmon layer. Bake for about 15-20 minutes, or until heated through and edges are golden brown.
Serve: Remove from the oven and allow to cool for a few minutes. Serve warm, garnished with nori strips and a side of soy sauce.
Notes
For an elegant presentation, serve in individual bowls with soy sauce on the side.
