Tips & Variations
- Use a very sharp knife dipped in water to slice the roll cleanly without crushing it.
- Substitute tempura shrimp with cooked crab or cooked scallops for different flavors.
- Adjust the amount of sriracha in the volcano sauce to control the heat level to your preference.
- For a vegan option, replace shrimp with tempura vegetables and use vegan mayonnaise.
Storage
Store leftover Volcano Roll in an airtight container in the refrigerator for up to 24 hours to maintain freshness. Reheating is not recommended as the texture of the tempura and rice will change, but you can enjoy it cold or at room temperature.

For Garnish
- 1 tablespoon eel sauce (optional)

Instructions
- Prepare the Sushi Rice: Rinse the sushi rice under cold water until the water runs clear to remove excess starch. Combine the rice and water in a rice cooker and cook according to the manufacturer’s instructions. Once cooked, gently stir in rice vinegar, sugar, and salt, then allow the rice to cool to room temperature.
- Assemble the Sushi Roll: Lay one sheet of nori onto a bamboo sushi rolling mat. Evenly spread a thin layer of the prepared sushi rice over the nori, leaving a 1-inch border at the top edge uncovered to help seal the roll.
- Add Fillings: Place 2 tempura shrimp, sliced avocado, and julienned cucumber along the bottom edge of the rice-covered nori.
- Roll the Sushi: Use the bamboo mat to carefully roll the sushi tightly away from you, pressing firmly to shape it. Wet the top border of the nori with a little water to seal the roll securely.
- Prepare Volcano Sauce: In a small bowl, mix together mayonnaise, sriracha sauce, soy sauce, sesame oil, and rice vinegar until well combined.
- Broil with Volcano Topping: Place the sushi roll on a baking sheet. Spread the volcano sauce evenly over the top of the roll. Broil in the oven for 2-3 minutes or until the sauce becomes bubbly and lightly browned.
- Slice and Garnish: Remove the roll from the oven and slice into bite-sized pieces using a sharp knife. Garnish each piece with sesame seeds, a drizzle of eel sauce if desired, and chopped green onions for a fresh finish.
Notes
- Rinsing the sushi rice thoroughly is essential to achieve the perfect sticky texture.
- Use a sharp knife dipped in water to slice the roll to avoid sticking and tearing.
- If you prefer a milder heat, reduce the amount of sriracha in the volcano sauce.
