Spicy Tuna Temaki Sushi with Avocado

**Cook the Sushi Rice:** Rinse the sushi rice under cold water until the water runs clear. Cook the rice according to package instructions or using a rice cooker. If using a saucepan, bring the rice and water to a boil, then reduce heat to low, cover, and simmer for 15-20 minutes, or until all the water is absorbed.

**Season the Rice:** While the rice is cooking, prepare the sushi vinegar mixture. In a small bowl, combine the rice vinegar, sugar, and salt. Stir until the sugar and salt are dissolved. Once the rice is cooked, transfer it to a large bowl and gently fold in the vinegar mixture. Let the rice cool slightly while you prepare the other ingredients.

**Prepare the Spicy Tuna:** In a medium bowl, combine the diced tuna, mayonnaise, sriracha, and sesame oil. Mix well to combine. Adjust the amount of sriracha to your preference for spiciness.

**Assemble the Temaki:** Have all your ingredients ready: seasoned sushi rice, spicy tuna mixture, sliced avocado, and nori seaweed triangles. To assemble, take a nori triangle and place a small amount of sushi rice in the center, spreading it thinly. Add a spoonful of the spicy tuna mixture and a few slices of avocado on top of the rice. Roll the nori into a cone shape, pressing gently to seal. The moisture from the rice will help it stick.

**Serve Immediately:** Serve the temaki sushi immediately with soy sauce, wasabi, and pickled ginger on the side, if desired. Enjoy the interactive experience of making your own sushi cones!
