Ingredients

• Sushi Rice: Use short-grain Japanese rice for its sticky texture that holds together perfectly when shaped and fried. Regular short-grain rice can work in a pinch, but authentic sushi rice delivers the best results.
• Rice Vinegar: Provides the signature tangy flavor in properly seasoned sushi rice. Don’t substitute with regular vinegar as it lacks the delicate sweetness of rice vinegar.
• Granulated Sugar: Balances the acidity of the vinegar in the sushi rice seasoning. Raw sugar can be substituted for a slightly different flavor profile.
• Kosher Salt: Use for seasoning the rice properly. The larger flakes dissolve nicely in the vinegar mixture.
• Grapeseed Oil: Perfect for frying due to its high smoke point and neutral flavor. Other neutral oils like canola or vegetable oil will work well too.
• Sushi-Grade Ahi Tuna: The star of the dish must be sushi-grade (meant to be consumed raw). Look for bright red color and purchase from a reputable fishmonger.
• Scallions: Adds fresh, mild onion flavor to the tuna mixture. Use both white and green parts for best flavor and color.
• Jalapeño: Provides fresh heat and vibrant color as a garnish. Serrano peppers make a good substitute for increased spiciness.
• Black Sesame Seeds: Offers visual contrast and subtle nutty flavor. White sesame seeds can be used if black ones aren’t available.
• Kewpie Mayonnaise: Japanese-style mayo that’s richer and creamier than American versions. The authentic choice for proper spicy mayo.
• Sriracha: Provides the heat and signature flavor in the spicy mayo. Adjust quantity based on desired spiciness.
• Ponzu Sauce: Citrus-based soy sauce that adds bright, tangy complexity to the spicy tuna mixture.

Variations

Vegetarian Crispy Rice

Replace the tuna with finely diced avocado mixed with the same spicy mayo mixture. The creamy texture of avocado creates a delicious contrast with the crispy rice. Add finely diced cucumber for extra crunch and refreshing flavor.

California Roll Style

Mix imitation crab meat with avocado and a touch of the spicy mayo. Top the crispy rice with this mixture and add a thin slice of avocado on top for a California roll-inspired variation that’s perfect for those who don’t eat raw fish.

Truffle Spicy Tuna

Elevate the dish by adding a few drops of truffle oil to the spicy tuna mixture and garnishing with microgreens. The earthy truffle flavor pairs beautifully with the rich tuna and spicy mayo for a truly luxurious bite.

How to Make the Recipe

Step 1: Prepare the Sushi Rice

Thoroughly rinse the rice until the water runs clear, removing excess starch. Cook according to package instructions, then season with the vinegar mixture while still warm, gently folding to maintain the rice’s integrity. Press into a flat layer and refrigerate overnight to set properly, which is crucial for achieving the right texture when frying.

Step 2: Prepare the Spicy Tuna Mixture

Finely chop the tuna to achieve the right texture—it should be small enough to spread easily but not so processed that it becomes mushy. Combine with sliced scallions and the spicy mayo mixture, balancing the creamy richness of Kewpie mayo with the heat of Sriracha and tanginess of ponzu. Refrigerate to allow flavors to meld.

Step 3: Fry the Rice Cakes

Cut the chilled rice into uniform rectangles, ensuring they’re compact enough to hold together during frying. Heat oil to the proper temperature before adding rice blocks, then fry until golden and crispy on both sides, creating that signature crunchy exterior while maintaining a tender interior.

Step 4: Assemble and Serve

Top each crispy rice piece with a generous spoonful of the spicy tuna mixture. Garnish with black sesame seeds and a thin slice of jalapeño, adding a final drizzle of spicy mayo if desired. Serve immediately while the rice is still warm and crispy for the perfect contrast with the cool tuna.

Tips for Making the Recipe

• Use a sharp knife dipped in water when cutting the rice blocks to prevent sticking and ensure clean edges
• When frying the rice, maintain a medium heat to ensure the outside gets crispy while the inside stays tender
• For the best texture, don’t skimp on refrigerating the rice overnight as this helps it firm up properly
• Purchase tuna from a trusted source that specializes in sushi-grade fish to ensure freshness and safety
• Pat the tuna dry before chopping to remove excess moisture, which helps achieve the ideal texture
• Make the spicy mayo slightly spicier than you think necessary, as the rice will temper the heat in the final dish

How to Serve

Serve these spicy tuna crispy rice bites immediately after assembly on a sleek rectangular plate or slate board for an impressive presentation. Arrange them in a single line or a grid pattern with small dishes of additional spicy mayo and soy sauce on the side for dipping. Pair with a cold Japanese beer, chilled sake, or a crisp white wine like Sauvignon Blanc to complement the rich flavors. For a complete meal, serve as an appetizer before a main course of miso soup and a simple green salad with ginger dressing.

Make Ahead

The components of this dish can be prepared in advance to make assembly quick and easy. The sushi rice can be cooked, seasoned, and shaped up to 2 days before, kept tightly wrapped in the refrigerator. The spicy tuna mixture can be prepared up to 24 hours ahead and stored in an airtight container in the refrigerator, though the freshest flavor comes from preparing it the same day. The spicy mayo sauce will keep for up to a week refrigerated. For best results, fry the rice cakes shortly before serving to maintain their crispiness, though they can be fried up to 2 hours ahead and kept at room temperature before topping.

FAQs

Is it safe to eat raw tuna at home?

Yes, as long as you purchase sushi-grade tuna from a reputable source. This designation means the fish has been frozen to kill potential parasites and handled properly to maintain freshness. Always keep it refrigerated and use within a day of purchase for optimal safety and flavor.

Can I make this with brown rice instead?

While traditional sushi rice provides the authentic texture and flavor, short-grain brown rice can be substituted. You’ll need to adjust the cooking time and may need slightly more liquid. The texture will be different—less sticky and slightly nuttier—but still delicious.

How can I make this recipe less spicy?

Easily adjust the heat level by reducing the amount of Sriracha in the spicy mayo. You can start with just 1-2 tablespoons instead of the full 1/4 cup, then taste and adjust. You can also omit the jalapeño garnish or replace it with cucumber for a cooling effect.

Can I prepare the rice in a rice cooker?

Absolutely! A rice cooker is actually ideal for preparing sushi rice as it creates consistent results. Use the same water-to-rice ratio recommended for sushi rice in your cooker, then season with the vinegar mixture after cooking.
