Cost: $29.51 total, $7.38 per serving

Ingredients

  • 2 cups Japanese Short‑Grain Sushi Rice (Rinsed until water runs clear; yields about 3 cups cooked rice)
  • 3 tablespoons Rice Vinegar (Seasoned with sugar and salt for sushi rice)
  • 1 tablespoon Granulated Sugar (To sweeten the rice vinegar mixture)
  • 1 teaspoon Salt (For the sushi rice seasoning)
  • 4 full sheets Nori Sheets (Cut each sheet in half; outer layer of the rice ball)
  • 8 ounces Imitation Crab Meat (Surimi) (Shredded or chopped; provides the classic California roll flavor)
  • 1 whole Avocado (Ripe, sliced into thin strips)
  • 1/2 medium Cucumber (Seeded and cut into match‑stick strips)
  • 2 tablespoons Mayonnaise (Optional; adds creaminess to the filling)
  • 1 teaspoon Toasted Sesame Seeds (For garnish and subtle nutty flavor)
  • to taste Soy Sauce (For dipping)

Instructions

  1. Rinse and Cook the Sushi Rice

    Place 2 cups of sushi rice in a fine‑mesh sieve and rinse under cold water until the water runs clear. Transfer to the rice cooker, add 2 ¼ cups water, and cook according to the cooker’s sushi rice setting (about 20 minutes).

    Time: PT20M

  2. Season the Cooked Rice

    While the rice is still hot, combine 3 Tbsp rice vinegar, 1 Tbsp sugar, and 1 tsp salt in a small bowl until dissolved. Gently fold the mixture into the rice using a wooden spoon or rice paddle. Spread the rice on a large plate to cool to room temperature.

    Time: PT10M

  3. Prepare the Fillings

    Shred the imitation crab, slice the avocado, and julienne the cucumber. In a small bowl, toss the crab with 2 Tbsp mayonnaise (optional). Set all fillings in separate piles on the countertop.

    Time: PT5M

  4. Line the Sushi Roll Shaper

    Lay a half‑sheet of nori (shiny side down) on the bottom of the shaper. If the shaper has a removable bottom, line it with a sheet of plastic wrap to prevent sticking.

    Time: PT2M

  5. Add the First Rice Layer

    Spread about ¼ cup of seasoned sushi rice evenly over the nori, leaving a ½‑inch border at the top edge.

    Time: PT2M

  6. Add Fillings

    Place a line of shredded crab, a few avocado strips, cucumber sticks, and a sprinkle of toasted sesame seeds across the middle of the rice layer.

    Time: PT2M

  7. Add the Top Rice Layer

    Cover the fillings with another ¼ cup of rice, again leaving the top border uncovered.

    Time: PT2M

  8. Press and Release the Rice Ball

    Close the shaper lid and press the button firmly for about 5 seconds. Open the shaper, flip it upside‑down, and the rice ball will pop out onto the plate.

    Time: PT1M

  9. Roll and Slice (Optional)

    If you prefer bite‑size pieces, roll the rice ball gently like a burrito and slice with a sharp knife into ½‑inch rounds. Otherwise, serve the whole ball as‑is.

    Time: PT3M

  10. Serve

    Arrange the rice balls on a serving plate, sprinkle any remaining sesame seeds, and serve with soy sauce for dipping.

    Time: PT2M
