Units Scale

Main Ingredients

  • 2 cups sushi rice (cooked)
  • 1 Tbsp rice wine vinegar
  • Big pinch of salt
  • 8 sticks imitation crab (shredded)
  • 1 Tbsp sriracha
  • 2.5 Tbsp kewpie mayo
  • Pinch of salt
  • 1 Persian cucumber (sliced in matchsticks)
  • 1 avocado (thinly sliced)
  • Furikake for sprinkling
  • 6 sheets square rice paper
  • 3 seaweed nori sheets
  • 23 Tbsp sesame seeds
  • Neutral Oil

Spicy Mayo Sauce

  • 1/4 cup kewpie mayo
  • 1 Tbsp tsp lime juice
  • 12 tsp sriracha sauce

Instructions

  1. Prepare sushi rice: Rinse the sushi rice thoroughly, then cook it in a pot or rice cooker according to package instructions. Once cooked, mix in rice wine vinegar and a pinch of salt. Let the rice cool to slightly warm or room temperature.
  2. Make imitation crab mixture: Shred the imitation crab using your hands by pulling each stick apart like string cheese. Add sriracha, kewpie mayo, and a pinch of salt, mixing until well combined.
  3. Prepare rice paper base: On a cutting board, brush with a thin layer of oil. Rehydrate one square sheet of rice paper in warm water, then place it on the cutting board. Rehydrate a second sheet and layer it on top of the first. Place a sheet of nori on top of the rice paper. Using scissors, cut a single slit from the center of the bottom edge of the square to the middle.
  4. Assemble sandwich: Spread about 2-3 Tbsp of imitation crab mixture on the bottom left section of the rice paper and nori. Add thinly sliced cucumber and avocado to the top left section. Spread an even 1/2-inch layer of rice over the top and bottom right sections. Be careful not to overstuff or it will be hard to fold!
  5. Fold sandwich: To fold, start with the bottom left section and fold it upwards. Fold the pouch to the right, then fold it down to form a compact sushi sandwich.
  6. Fry sandwich: Heat a generous amount of neutral oil in a pan over medium heat. Add the sushi sandwiches and fry on medium-high heat for 3-4 minutes on one side until crispy. Flip and fry the other side for another 3-4 minutes.
  7. Serve: Serve warm and crispy with spicy mayo sauce on the side.

Notes

  • Be careful not to overstuff the sandwich or it will be hard to fold.
