Sushi Ingredients

Spicy Tuna Filling

Vegetable Fillings

Method

Prepare Sushi Rice

  1. 1

    Rinse Rice

    Rinse 2 cups of sushi rice under cold water until the water runs clear to remove excess starch.

  2. 2

    Cook Rice

    In a rice cooker or pot, combine the rinsed sushi rice and 2.5 cups of water. Cook according to the rice cooker's instructions or bring to a boil, then reduce heat to low, cover, and simmer for 20 minutes.

  3. 3

    Season Rice

    Once cooked, remove the rice from heat. In a small bowl, mix 1 tablespoon of rice vinegar, 1 teaspoon of sugar, and 0.5 teaspoon of salt until dissolved. Gently fold this mixture into the rice while it's still warm. Let the rice cool to room temperature.

Prepare Spicy Tuna Filling

  1. 4

    Chop Tuna

    Finely chop 8 oz of sushi-grade tuna and place it in a mixing bowl.

  2. 5

    Mix Ingredients

    Add 2 tablespoons of mayonnaise, 1 tablespoon of sriracha sauce, 2 tablespoons of finely chopped green onion, and 0.5 teaspoon of sesame oil to the tuna. Mix well to combine.

Prepare Vegetables

  1. 6

    Slice Cucumber

    Cut the cucumber into thin strips.

  2. 7

    Slice Avocado

    Cut the avocado in half, remove the pit, and slice the flesh into thin slices.

Assemble Sushi Rolls

  1. 8

    Lay Nori

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

  2. 9

    Add Rice

    With wet hands, spread an even layer of sushi rice over the nori, leaving a 1-inch border at the top.

  3. 10

    Add Fillings

    In the center of the rice, place a line of the spicy tuna mixture, followed by a few strips of cucumber and avocado.

  4. 11

    Roll 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. 12

    Slice Rolls

    Use a sharp, wet knife to slice the sushi roll into 6-8 pieces.
