01 - Rinse sushi rice under cold water until water runs clear. Combine rice and water in a saucepan; bring to a boil. Reduce heat to low, cover, and simmer for 10 minutes. Remove from heat and let stand, covered, for 10 additional minutes.
02 - Whisk together rice vinegar, sugar, and salt in a small bowl until dissolved. Gently fold the seasoning mixture into the cooked rice using a paddle or spatula. Set aside to cool slightly.
03 - Combine soy sauce, sesame oil, rice vinegar, honey, and sriracha in a medium bowl. Whisk until well blended. Add diced salmon and toss gently to coat. Refrigerate for 10 minutes to marinate.
04 - Slice avocados, cucumbers, and radishes into thin rounds. Julienne the carrot into matchstick strips. Finely slice green onions. Keep all components chilled until assembly.
05 - Divide seasoned rice evenly among four serving bowls. Arrange marinated salmon, avocado slices, cucumber, edamame, carrot, radishes, and green onions in sections over the rice.
06 - Drizzle remaining poke sauce over each bowl. Sprinkle with sesame seeds and add nori strips or pickled ginger if desired. Serve immediately while components are fresh and chilled.
