Prepare the sushi rice: Rinse the rice 3 or 4 times until the water runs clear. Add to a pan with 330ml of water and bring to the boil. Cover and simmer for 10 minutes. Remove from heat and leave with lid on to steam for 20 minutes. Mix in a bowl with the sushi rice seasoning and stir lightly with a wooden spoon until it reaches somewhere near room temperature. Use a fan to speed this process up.

Prepare the filling: Mix the honey, soy sauce and garlic powder together in a small bowl with a little hot water from a kettle. Gently pan-cook the salmon fillets for a couple of minutes, then add the teriyaki sauce. Gently flake the salmon as it cooks. The sauce should be reduced to a sticky reside that covers the salmon flakes.

Wet your hands, then take a handful of the sushi rice and roll into a ball. Then form into a cup-shape and fill with some of the salmon. Push the edges of the cup together, adding a little more rice if needed so the salmon is completely covered. Then form into a shape of your choice - balls are good, but go for a traditional Japanese triangle/wedge shape for real authenticity.

Take a sheet of sushi nori and place around the cake, leaving plenty of rice exposed. A single short strip of nori folded around the bottom of the cake is the easiest approach, or you can completely cover the bottom of the cake as shown in the photo - use a little water as 'glue' to make the nori stick.
