Sushi Rice

Truffle Sauce

Method

Prepare Sushi Rice

  1. 1

    Rinse the Rice

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

  2. 2

    Cook the Rice

    Combine the rinsed rice and 2.5 cups of water in a rice cooker and cook according to the manufacturer's instructions. Once done, let it sit covered for 10 minutes.

  3. 3

    Season the Rice

    In a small bowl, mix 1 tablespoon of rice vinegar, 1 teaspoon of sugar, and 1 teaspoon of salt until dissolved. Fold this mixture into the cooked rice gently. Allow the rice to cool to room temperature.

Prepare Fish and Vegetables

  1. 4

    Slice the Fish

    Using a sharp knife, slice the tuna, Ora King salmon, and hamachi into thin strips, approximately 1/4 inch thick.

  2. 5

    Prepare the Cucumber

    Cut the cucumber in half lengthwise, then slice it into thin strips.

Make Truffle Sauce

  1. 6

    Combine Ingredients

    In a small bowl, mix together 2 tablespoons of truffle oil, 1 tablespoon of soy sauce, and 1 teaspoon of sesame oil. Stir well.

Assemble the Roll

  1. 7

    Lay Out the Nori

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

  2. 8

    Add Sushi Rice

    Wet your hands to prevent sticking, and take a handful of sushi rice. Spread it evenly over the nori, leaving about 1 inch at the top edge.

  3. 9

    Layer the Fillings

    In the center of the rice, layer slices of tuna, Ora King salmon, hamachi, and cucumber strips.

  4. 10

    Drizzle Truffle Sauce

    Drizzle a small amount of the truffle sauce over the fish and cucumber.

  5. 11

    Roll the Sushi

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

  6. 12

    Cut the Roll

    Using a sharp knife, slice the roll into 6-8 pieces. Wipe the knife with a damp cloth between cuts to ensure clean slices.

  7. 13

    Garnish and Serve

    Sprinkle the sliced sushi with toasted sesame seeds. Serve with extra truffle sauce for dipping.
