First up, make your sushi rice. Place one cup of sushi rice into a saucepan and rinse thoroughly (wash, drain, and repeat 3 times). Then, add in one cup of cold water and place on medium heat.
Once bubbles start forming around the edges of the rice, reduce to low heat and place the lid onto the pan. Cook for 10 minutes. Do NOT take off the lid.
Then, after 10 minutes, turn off the heat but keep the lid on for another 5 minutes.
Meanwhile, in a small bowl, combine your sugar, rice wine vinegar, salt, and boiling water. Mix and then once the rice has rested for the extra 5 minutes, remove the lid and pour it over the rice. Combine thoroughly, then transfer the rice to a large bowl to cool.
Next up, add your cubed fillet of salmon into a bowl and pour in your soy sauce, sesame oil, salt, and pepper. Toss and then set it aside in the fridge.
Get your nori sheets placing them on a chopping board, and using a small bowl, place it upside down onto your nori sheets and cut out a circular taco-shape into the nori. Keep the leftover nori pieces in an airtight container and save for another recipe.
Place a nori sheet on a chopping board and place 3 heaped tablespoons of sushi rice. Using a fork, gently spread out the rice to the edges of the nori sheet.
On one side of the nori sheet along the vertical centre of the sushi, place down your avocado slices. On the other side along the vertical centre of the wrapper, place down ¼ of your salmon.
Top with pickled ginger, drizzle with sriracha mayonnaise, sprinkle over sesame seeds and repeat for the other 3 sushi tacos. Enjoy!
