Ingredients

• For the sushi rice
• 2 cups sushi rice (short grain)
• 2 cups water
• ¼ cup rice vinegar
• 2 tablespoons sugar
• 1 teaspoon salt
• For the filling
• 8 ounces sushi-grade tuna (see safety note below for alternatives)
• ½ English cucumber, thinly sliced into matchsticks
• 1 ripe avocado, thinly sliced
• 2 scallions, thinly sliced
• 1 tablespoon fresh lime juice
• Optional: pinch of salt
• For assembly
• 4 sheets nori seaweed sheets
• Optional: 2 tablespoons toasted unsweetened shredded coconut (for light sprinkle inside OR on the outside)

Directions

1. Cook the Rice: First things first, rinse your sushi rice under cold water until the water runs clear. This removes excess starch and is crucial for perfect sticky rice. Combine the rinsed rice and water in a medium pot or rice cooker. If using a pot, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let it rest, covered, for another 10 minutes.
2. Season the Rice: While the rice rests, whisk together the rice vinegar, sugar, and salt in a small bowl until the sugar and salt dissolve. Once the rice is ready, transfer it to a large, non-metallic bowl. Pour the seasoned vinegar mixture evenly over the rice. Using a cutting motion with a rice paddle or wooden spoon, gently fold the seasoning into the rice. Avoid mashing!
3. Cool Properly: Spread the seasoned rice out in a thin layer in the bowl. To cool it down to warm room temperature quickly, you can fan it gently (a clean piece of cardboard works great!). Once cooled, cover the rice with a damp, clean kitchen towel to keep it from drying out while you prepare your fillings.
4. Prep the Filling: Slice your cucumber and avocado into thin strips. For the tuna, dice it into small, even pieces. In a small bowl, gently toss the diced tuna with the lime juice and an optional pinch of salt. Slice your scallions finely.
5. Set Up Rolling Station: Lay your bamboo rolling mat (or a clean kitchen towel covered with plastic wrap) on a clean, flat surface. Have your nori sheets, the cooled sushi rice, your prepared fillings, and a small bowl of water (for wetting your hands) nearby. Keep a damp towel handy for wiping your knife later.
6. Build the Roll: Place one nori sheet shiny-side down on your bamboo mat, aligning it with the edge closest to you. Dip your hands in the water to prevent sticking, then grab a small handful of rice (about ½ cup). Spread the rice evenly over about ¾ of the nori sheet, leaving the top 1 inch bare. The rice layer should be thin—you should almost be able to see the nori through it.
7. Add Filling: Arrange a thin line of your tuna, cucumber, avocado, and scallions horizontally across the center of the rice-covered nori. Remember, less is more here to ensure a tight roll! If using, lightly sprinkle some toasted coconut over the filling.
8. Roll with Pressure: Using your thumbs to lift the mat, fold the edge of the nori closest to you up and over the filling, tucking it in tightly. Gently press down on the roll with your fingers as you continue to roll forward, applying even pressure to keep it tight. Once you reach the bare strip of nori, wet it lightly with a finger dipped in water to help seal the roll. Roll completely to seal.
9. Cut Cleanly: Place the rolled sushi seam-side down on a cutting board. Using a very sharp, damp knife, slice the roll in half, then cut each half into 3 or 4 equal pieces (for a total of 6-8 pieces per roll). Wipe your knife with a damp towel between each cut to prevent sticking and ensure clean slices. Serve immediately!
