Make sushi rice: Rinse the rice and add to the rice cooker. Then add water and cook according to the instructions. Once cooked, transfer to a large bowl and let it cool. When it’s still very warm, mix in the sushi vinegar (or the mixture of rice vinegar, sugar, and salt).
Make spicy Sriracha mayo sauce: In a clear bowl, mix together Sriracha sauce and mayonnaise. Taste and add more Sriracha if you prefer a spicier flavor.
Make the filling: Shred the imitation crab meat using your hands or two forks.
Mix the Sriracha sauce and myo. Add the sauce to the shredded crab and mix well.
Assemble the roll: Cover the bamboo mat with plastic wrap. Cut the nori sheet into two halves with kitchen scissors. Place half of a nori sheet on top of the bamboo mat shiny side facing down.
Spread seasoned sushi rice (about 3/4 cup) over nori evenly. Press the rice gently with your hands. (Tips: You can dip your hands in Tezu water to prevent the rice from sticking to your hands).
Sprinkle sesame seeds on top of the rice.
Flip the sheet and let the rice side facing down.
Add the spicy Kani crab salad to the middle of the nori sheet.
Place the thumbs underneath the bamboo mat and lift the edge up and over the filling.
Roll the bamboo mat away from you and press the rice and filling together. Keep rolling until the ends meet.
Move the roll to a cutting board and cut it into 8 pieces.
Drizzle more spicy mayo sauce on top of the roll for some extra heat.
