Rinse and cook short grain rice according to package directions.

In a small saucepan over medium-low heat, whisk together rice vinegar, sugar, and kosher salt until completely dissolved. Pour this mixture over the cooked rice and fan with a rice paddle to evenly distribute the seasoning.

Line an 8-by-8-inch baking pan with plastic wrap. Gently press the seasoned rice into an even layer, then cover with another piece of plastic wrap. Avoid over-compressing the rice. Place in freezer for 3 hours to firm up.

While rice is chilling, dice salmon into ¼-inch cubes and place in a bowl. Combine with mayo, sriracha, soy sauce, toasted sesame oil, and chopped green onion. Toss until well mixed, cover, and refrigerate until needed.

Once rice is firm, cut into 18 rectangles (6 columns by 3 rows). Heat ½-inch of oil in a wide-rimmed pan over medium heat. Working in batches, fry rice blocks until golden brown and crispy, about 1-2 minutes per side. Adjust heat if browning too quickly. Transfer to paper towel-lined plate to drain.

Once rice blocks have cooled to room temperature, top each with a slice of avocado, a spoonful of spicy salmon mixture, a jalapeño slice, a drizzle of toasted sesame oil, sweet chili sauce, and a sprinkle of toasted sesame seeds. Serve immediately.
