Sushi Rice

Nori and Garnish

Method

Prepare Sushi Rice

  1. 1

    Rinse and Cook Rice

    Rinse 2 cups of sushi rice under cold water until the water runs clear. Cook the rice according to your rice cooker instructions or by boiling in water (use a 1:1 ratio of rice to water).

  2. 2

    Season the Rice

    Once the rice is cooked, transfer it to a large bowl. In a separate small bowl, mix 3 tablespoons of rice vinegar, 1 tablespoon of sugar, and 1 teaspoon of salt until dissolved. Pour this mixture over the rice and gently fold it in with a wooden spatula. Allow the rice to cool to room temperature.

Prepare Sushi Ingredients

  1. 3

    Prepare Avocado

    Cut the avocado in half, remove the pit, and scoop out the flesh. Slice the avocado into thin strips and set aside.

  2. 4

    Prepare Shrimp Tempura

    If not pre-cooked, prepare shrimp tempura according to package instructions or your preferred method. Ensure they are crispy and ready to use.

Assemble the Volcano Roll

  1. 5

    Lay Nori on Bamboo Mat

    Place a sheet of nori, shiny side down, on a bamboo sushi mat.

  2. 6

    Spread Sushi Rice

    Wet your hands to prevent sticking, then grab a handful of sushi rice and evenly spread it over the nori, leaving a 1-inch border at the top.

  3. 7

    Add Fillings

    In the center of the rice, add a line of shrimp tempura, cream cheese, spicy kani, and avocado slices.

  4. 8

    Roll the Sushi

    Using the bamboo mat, carefully roll the sushi away from you, pressing gently but firmly to keep the roll tight. Seal the edge of the nori with a little water.

  5. 9

    Slice the Roll

    Using a sharp, wet knife, slice the roll into 8 equal pieces.

  6. 10

    Garnish with Tobiko and Spicy Mayo

    Sprinkle tobiko on top of the sushi roll and drizzle with spicy mayo. Optionally, sprinkle sesame seeds for added flavor.
