  • Total Time: 1 hour 25 minutes
  • Yield: 32 bite-sized pieces

Ingredients

  • 2 cups sushi rice, rinsed until water runs clear
  • 2 ¼ cups water
  • ½ teaspoon salt
  • 3 tablespoons rice vinegar
  • 1 tablespoon granulated sugar
  • 1 teaspoon sesame oil
  • 8 oz sushi-grade ahi tuna, finely chopped
  • 3 tablespoons Japanese kewpie mayonnaise
  • 12 tablespoons sriracha (adjust to taste)
  • 1 teaspoon soy sauce (for sushi/sashimi)
  • 1 teaspoon sesame oil
  • 1 teaspoon lime juice
  • 1 avocado, thinly sliced
  • 1 tablespoon toasted sesame seeds
  • 2 tablespoons chives or scallions, minced
  • 1 jalapeño or serrano pepper, thinly sliced
  • Vegetable oil, for frying

Instructions

  1. Rinse sushi rice until water runs clear, then cook with water and salt in a rice cooker.
  2. Mix rice vinegar, sugar, and sesame oil until dissolved. Toss with hot rice.
  3. Press rice into a lined baking pan (about ½-inch thick). Cover and refrigerate 1 hour, or freeze 30 minutes, until firm.
  4. Cut chilled rice into small rectangles.
  5. Heat vegetable oil in a skillet. Fry rice rectangles until golden and crispy on both sides. Drain on a wire rack.
  6. Mix chopped tuna with kewpie mayonnaise, sriracha, soy sauce, sesame oil, and lime juice.
  7. Assemble by topping crispy rice with avocado slices, a spoonful of spicy tuna, sesame seeds, chives, and a jalapeño slice. Serve immediately.

Notes

  • Swap ahi tuna with sushi-grade salmon for variation.
  • Lightly sear tuna for a cooked version.
  • Air fry rice squares for a lighter alternative to deep frying.
  • Add a drizzle of eel sauce for sweetness.
  • Best eaten fresh; prepare rice block ahead but fry the day of serving.
