For the sushi rice:
-
1 cup sushi rice (or other short-grain rice)
-
2 tablespoons rice vinegar
-
1 ½ teaspoons granulated sugar
-
½ teaspoon kosher salt
-
½ cup grapeseed oil (or other neutral oil for pan-frying)
For the spicy tuna topping:
-
½ lb sushi-grade ahi tuna, finely chopped
-
3 scallions, thinly sliced
-
1 jalapeño, thinly sliced (for garnish)
-
Black sesame seeds (for garnish)
For the spicy mayo:
-
½ cup Kewpie mayonnaise
-
¼ cup Sriracha
-
3 tablespoons ponzu sauce
Directions
-
Prepare the Sushi Rice: Rinse the rice thoroughly under cool water until the water runs clear. Cook the rice according to the package instructions or using a rice cooker.
-
Season the Rice: In a small saucepan, combine the rice vinegar, sugar, and salt. Heat over medium-high until dissolved, then pour this mixture over the cooked rice. Gently mix.
-
Cool and Shape the Rice: Transfer the rice to a lined baking dish or container. Press into a flat, even layer (~½” thick). Cover and refrigerate for at least 3 hours or overnight. Once firm, cut into bite-sized rectangles (~2″ x ¾”).
-
Make the Spicy Tuna Mixture: Finely chop the tuna. In a bowl, mix the tuna, sliced scallions, Kewpie mayo, Sriracha, and ponzu sauce until well combined. Refrigerate until needed.
-
Fry the Crispy Rice: Heat the grapeseed oil in a pan over medium heat. Fry the rice pieces for about 2 minutes per side until golden brown and crispy. Drain on a wire rack.
-
Assemble: Spoon a heaping tablespoon of the spicy tuna mixture onto each crispy rice piece. Garnish with sesame seeds and a slice of jalapeño. Serve immediately with extra spicy mayo if desired.

FAQs
How do I get the rice crispy?
Make sure to chill the rice after seasoning and before frying. This helps the rice firm up and hold its shape when frying.
Can I use a different type of tuna?
Yes, you can substitute with spicy salmon, yellowtail, or even cooked shrimp for variation.
Can I make this ahead of time?
You can prepare the rice and spicy tuna mixture a few hours ahead of time. Just assemble the dish right before serving.
What type of oil should I use for frying?
Use a neutral oil with a high smoke point, like grapeseed or vegetable oil, to ensure a crispy, golden-brown crust without burning.
Can I use store-bought mayo?
Kewpie mayo is preferred for its rich, slightly sweet flavor, but you can substitute regular mayonnaise if needed.
