Rinse the sushi rice under cold water until the water runs mostly clear. Cook with water according to package instructions or in a rice cooker.
In a small bowl, mix rice vinegar, sugar, and salt. Warm slightly if needed to dissolve. Gently fold the mixture into the cooked rice. Let cool slightly.
Step 2 Make the Salmon Mixture
In a medium bowl, combine flaked salmon, Japanese mayonnaise, cream cheese, soy sauce, and sriracha if using. Stir until creamy and well blended.
Step 3 Assemble
Preheat oven to 375 degrees.
Press the seasoned rice evenly into the bottom of a greased 9 by 9 inch baking dish. Sprinkle half the furikake over the rice.
Spread the salmon mixture evenly over the top. Sprinkle remaining furikake on top.
Step 4 Bake
Bake for 15 to 20 minutes, or until heated through and slightly golden on top.
Step 5 Garnish and Serve
Top with green onions, avocado, and an extra drizzle of spicy mayo if desired.
Serve warm with nori sheets. Scoop a spoonful onto the nori and fold like a taco.
Notes
Use short grain sushi rice for best texture. Long grain rice will not hold together properly.• Let the rice cool slightly before spreading the salmon mixture on top. This keeps the layers distinct.• Do not overbake. The goal is to heat through and lightly warm the top, not dry it out.• Adjust the sriracha to your heat preference. Start small and add more after baking if needed.• For extra texture, sprinkle additional furikake or toasted sesame seeds after baking.• Serve immediately with crisp nori sheets. The nori softens quickly once topped.• This recipe works well with leftover baked salmon, canned salmon, or even smoked salmon.• To make it without cream cheese, simply replace it with additional Japanese mayonnaise for a lighter texture.• Store leftovers covered in the refrigerator for up to 3 days. Reheat gently and add fresh toppings before serving.
