Ingredients
A great sushi roll starts with perfectly prepared rice and high-quality fillings.

- Servings: ¼ cup
- Sriracha – The source of our signature heat.
- Servings: 1-2 tbsp, or to your taste
- Toasted Sesame Oil: 1 tsp
- Scallion: 1, finely sliced
- Tempura Flakes (Tenkasu) – These are crispy bits of fried tempura batter and provide the essential crunch. You can find them at Asian markets or online.
- Servings: ½ cup

Spice Profile Breakdown
The spice in this roll is creamy, garlicky, and vibrant, with a sharp kick available from wasabi.
| Spice/Aromatic | Flavor Role | Optional Substitution |
|---|---|---|
| Sriracha | Provides the primary creamy, garlicky, and vinegary heat for the tuna filling. | Sambal oelek for a purer chili heat, or gochujang for a fermented, sweeter heat. |
| Wasabi | Served on the side, it offers a sharp, pungent, and sinus-clearing heat that is a classic sushi pairing. | A small amount of prepared horseradish can provide a similar sharp kick. |
| Ginger (Pickled) | Acts as a sweet, tangy, and slightly spicy palate cleanser between bites. | There is no good substitute for pickled sushi ginger. |
| Scallion | Adds a fresh, mild, and sharp oniony bite to the spicy tuna mixture. | Finely minced chives can be used instead. |
Essential Tools
Making sushi at home is much easier with these key tools.
- Bamboo sushi rolling mat (makisu)
- Rice cooker or pot
- Rice paddle or wide wooden spoon
- A very sharp knife
- Small bowls for water and fillings
Cooking Instructions
Follow these steps for a perfect, restaurant-quality roll every time.
Step 1: Master the Perfect Sushi Rice
This is the foundation of great sushi. Rinse the uncooked sushi rice in a bowl with cold water, swishing it around, until the water runs clear.
Cook the rice according to your rice cooker’s instructions or on the stovetop. While the rice is cooking, gently heat the rice vinegar, sugar, and salt in a small saucepan until the sugar and salt dissolve; do not let it boil.
Once the rice is cooked, transfer it to a large, non-metallic bowl. Drizzle the vinegar mixture over the hot rice and use a cutting and folding motion with a rice paddle to mix it in and separate the grains.
Let the rice cool to room temperature before rolling.
Step 2: Create the Fiery Tuna Filling
While the rice cools, prepare your filling. Pat the sushi-grade tuna completely dry with paper towels. Using a very sharp knife, dice the tuna into small, ¼-inch cubes.
In a medium bowl, combine the Japanese mayonnaise, sriracha, and toasted sesame oil, and whisk until smooth.
Add the diced tuna and the finely sliced scallion to the bowl. Gently fold everything together until the tuna is evenly coated in the creamy, spicy sauce. Be careful not to mash the tuna.
Step 3: The Art of the Roll
Now for the fun part! Place your bamboo rolling mat on a flat surface. You can wrap it in plastic wrap for easy cleanup.
Place one sheet of nori on the mat with the shiny side down. Have a small bowl of water nearby. Dip your fingers in the water (this is called tezu) to prevent the rice from sticking to them.
Scoop about ¾ cup of the cooled sushi rice and spread it evenly over the nori, leaving a ½-inch border at the top edge.
Be gentle and don’t press down too hard.
Step 4: Fill, Tuck, and Roll
About one inch from the bottom edge of the rice, create a channel of your fillings. Start with a line of the spicy tuna mixture.
Right next to it, sprinkle a generous line of the crispy tempura flakes. This is your crunchy element! If you’re using avocado or cucumber, place them here as well. Now, begin to roll. Lift the edge of the mat closest to you, and use it to fold the bottom of the nori and rice tightly over the fillings.
Tuck the edge in firmly to create a compact cylinder, then continue to roll the mat forward, applying gentle, even pressure, until you reach the bare nori at the top.
Moisten the top edge with a little water and complete the roll to seal it.
Step 5: Slicing and Serving
The secret to clean slices is a wet, sharp knife. Dip the tip of your sharpest knife in water and let the water run down the blade.
First, trim off the very ends of the roll for a clean presentation. Then, slice the roll in half. Line up the two halves and slice them into 3 or 4 pieces each, for a total of 6 or 8 pieces per roll. Wipe and re-wet your knife between cuts as needed.
Arrange your beautiful crunchy spicy tuna roll pieces on a platter and serve immediately with soy sauce, pickled ginger, and a dab of wasabi.
Recipe Variations
This roll is a perfect base for your own sushi creations.
- Make it “Inside-Out” (Uramaki): Spread the rice on the nori, then flip it over so the nori is on top. Add your fillings and roll it up. Coat the outside of the rice in toasted sesame seeds or tobiko (flying fish roe).
- Spicy Salmon or Yellowtail: Simply substitute the sushi-grade tuna with sushi-grade salmon or yellowtail for a different flavor.
- Add Cream Cheese: For an American-style roll, add a thin strip of cream cheese along with the tuna and tempura flakes.
Serving Suggestions
A great sushi roll is the star of the show, but a few accompaniments complete the meal.
- Edamame: A bowl of steamed and lightly salted edamame is the perfect starter.
- Miso Soup: A small, savory bowl of miso soup is a classic and comforting pairing.
- Seaweed Salad (Goma Wakame): A sweet and savory seaweed salad is a refreshing side dish.
Storage & Reheating Tips
Sushi is a dish that is meant to be eaten fresh.
- Storage: Sushi is at its absolute best within a few hours of being made. If you must store leftovers, wrap the rolls tightly in plastic wrap and refrigerate for up to 24 hours. The rice will harden and the crunch will soften, but it will still be edible.
- Reheating: Do not reheat sushi. It is meant to be eaten cold or at room temperature.
Common Mistakes & Fixes
Here are some quick tips to help you on your sushi-making journey.
| Mistake | Fix |
|---|---|
| My rice is a sticky, mushy mess. | You likely used the wrong type of rice or overcooked it. Use only Japanese short-grain “sushi” rice, and be sure to rinse it well. Spreading it out to cool with the vinegar mixture is also key. |
| My roll is falling apart. | You didn’t roll it tightly enough. The first tuck is the most important part. Make sure you pull that first edge snugly over the filling and apply gentle, even pressure as you continue to roll. |
| The nori is tearing as I spread the rice. | Be gentle! You don’t need to press down hard. Use wet fingertips and a light touch to guide the rice across the nori. Also, ensure your nori is fresh and not brittle. |
| My slices are squished and messy. | Your knife is not sharp enough or wet enough. Use your sharpest knife, and dip the blade in water before each cut. Use a long, single slicing motion rather than sawing back and forth. |
| I can’t find tempura flakes. | You can make a great substitute! Simply toast some panko breadcrumbs in a dry skillet over medium heat until they are golden-brown and fragrant. They provide a wonderful crunch. |
FAQs
Here are answers to a few more essential sushi questions.
What is “sushi-grade” tuna and is it safe?
“Sushi-grade” or “sashimi-grade” is a term used by fish sellers to indicate that the fish is of the highest quality and they consider it safe to be eaten raw.
It is typically flash-frozen at very low temperatures to kill any potential parasites. Always buy from a reputable fishmonger you trust.
Do I absolutely need a bamboo rolling mat?
While a makisu makes rolling much easier and more uniform, you can make a roll without one in a pinch.
You can use a clean kitchen towel or a flexible placemat covered in plastic wrap. It will just be a bit more challenging to get a tight, even roll.
How do I make the roll less spicy?
The spice level is very easy to control. Simply reduce the amount of sriracha in your spicy mayo.
Start with just one teaspoon, taste, and add more until it reaches a heat level you enjoy.
