TIP: To make the seasoned sushi rice, rinse 1 cup of uncooked sushi rice in cold water several times, then drain. Transfer to a rice cooker and add 1 cup water. Once cooked, transfer to a large prep bowl. Using a wooden paddle, gently spread the grains to allow to slightly cool. Season with 1 teaspoon rice vinegar, 1 teaspoon sugar and ¼ teaspoon salt. Allow the rice to come to room temperature before assembling your rolls.
