Cook the Rice
Cook 2 cups of short-grain Japanese rice in a rice cooker or pot. Once done, let it cool slightly.
Prepare the Salmon
Lightly salt the salmon fillet (if not pre-salted).
Pan-fry or grill until fully cooked. Flake the salmon into small pieces with a fork.
Mix the Filling
In a small bowl, combine the flaked salmon and shio kombu. Set aside.
Season the Rice
Gently stir a pinch of salt into the warm rice to enhance its flavor.
Shape the Onigiri
Wet your hands with water, sprinkle them with a little salt, and scoop about ½ cup of rice into your palm.
Flatten the rice slightly and place a spoonful of the salmon-shio kombu mixture in the center.
Shape the rice into a triangle or ball, enclosing the filling securely.
Wrap with Nori
Wrap each onigiri with a strip of nori, shiny side out, or leave plain if preferred.
Serve or Store
Serve immediately or wrap in cling film to keep fresh.
