Crispy Spicy Tuna Recipe

1. Prepare seasoned sushi rice: while rice is warm, fold in rice vinegar, sugar and kosher salt until evenly distributed. Spread rice thinly on a sheet pan lined with plastic wrap to cool to room temperature (about 15–20 minutes).

2. Form rice into 6 even patties: wet hands to prevent sticking and press about 1/3 cup of rice per patty into 2.5–3 inch rounds, approximately 1/2 inch thick. Place patties on a parchment-lined tray and refrigerate 10 minutes to firm up.

3. Dust each rice patty lightly with potato starch or cornstarch on both sides to help crisping and prevent batter slippage.

4. Heat oil in a medium skillet to 350°F (175°C). If you don’t have a thermometer, test by dropping a pinch of batter—it should sizzle immediately and brown in ~30 seconds.

5. Fry rice patties: working in a single layer (do not overcrowd), fry each patty 1–2 minutes per side until golden brown and crisp. Use tongs or a slotted spatula to flip carefully. Drain on paper towels and keep warm in a low oven (200°F / 95°C) while finishing remaining patties.

6. Make a very light tempura batter just before frying: in a bowl, whisk together flour, cornstarch and salt. If using egg, beat it lightly and stir into the ice-cold sparkling water, then fold into dry ingredients with a few quick strokes—batter should be lumpy and cold. Keep batter refrigerated until ready to use.

7. Optional: For an extra thin crispy layer, dip each dusted rice patty briefly into the batter and immediately fry as directed above. If you prefer a dry crust, skip the batter step and fry dusted patties directly.

8. Prepare tuna: pat the diced sushi-grade tuna dry with paper towel and place in a chilled bowl.

9. Combine dressing: in a small bowl mix mayonnaise, Sriracha, gochujang (if using), soy sauce, sesame oil and lime juice until smooth.

10. Fold dressing into tuna: add dressing to tuna along with sliced green onion and sesame seeds; gently fold to coat evenly. Taste and adjust salt or heat (add more Sriracha if desired). Keep chilled until assembly.

11. Slice avocado thinly and keep slices ready. Thinly slice jalapeño.

12. Place 6 warm crispy rice bases on a serving plate.

13. Top each crispy rice base with about 1 heaping tablespoon (approximately 15 g) of spicy tuna tartare, pressing gently so it sits on the rice.

14. Fan or place 2–3 avocado slices on each piece beside or slightly under the tuna for presentation.

15. Add 1–2 thin jalapeño rings to each piece for heat and visual contrast.

16. Spoon about 1 teaspoon of tobiko on top of each tartare mound (reserve remaining tobiko for garnish).

17. Drizzle each piece lightly with sweet soy glaze or unagi-style sweet sauce—about 1/2 teaspoon per piece. For a glossy finish, warm the sauce slightly before drizzling.

18. Finish with a sprinkle of microgreens or chives and an extra pinch of sesame seeds if desired.

19. Serve immediately while rice bases are still warm and crispy. Provide extra sauce on the side.
