On top goes a layer of lime-kissed avocado, a mound of spicy tuna tartare tossed with Kewpie mayo and sriracha, and a final drizzle of sweet soy glaze. The result is a bite-sized appetizer that feels both playful and refined, perfect for parties, game-day spreads, or a special treat.

Ingredients

Why this recipe works

The key to getting that dramatic crispy exterior is to press the seasoned sushi rice firmly into a dish and freeze it until completely firm. This step allows the rice to hold its shape when cut and fried, so each piece develops a deep golden crust without falling apart. The freezing also ensures the interior stays tender and slightly chewy, creating a wonderful textural contrast with the crunchy exterior.

Pan-frying the rice in a generous amount of hot oil is what gives it that all-around crackling crust. Frying each side for about 3 minutes ensures even browning and a satisfying crunch.

The high heat quickly caramelizes the surface, while the inside remains moist and cohesive. This method is similar to making arancini or fried rice cakes, but with a lighter, more delicate texture that pairs perfectly with the fresh tuna.

Notes and substitutions

Sushi rice is essential here because it is short-grain and sticky, which makes it easy to press and fry without falling apart. If you can't find sushi rice, use another short-grain rice like Calrose or Arborio. Season the rice while it is still warm so the vinegar and sugar absorb evenly. The rice should be slightly firm and not overly wet—if it is too sticky, let it cool a bit before pressing.

For the tuna, always buy sushi-grade or sashimi-grade from a trusted fishmonger. Keep it very cold until the moment you dice it, and use a sharp knife to make clean cuts.

Kewpie mayonnaise is richer and more tangy than regular mayo, but you can substitute with regular mayo and a touch of rice vinegar. The sweet soy glaze is available in Asian markets, or you can make your own by simmering soy sauce, honey, and rice vinegar until syrupy.

• Kewpie mayonnaise: Regular mayonnaise (use 2 tbsp regular mayo plus 1 tsp rice vinegar for tang)
• Sushi-grade tuna: Fresh salmon or hamachi (sushi-grade), or use cooked shrimp for a safer option
• Sweet soy glaze: Mix 2 tbsp soy sauce, 1 tbsp honey, and 1 tsp rice vinegar; simmer until syrupy
• Sushi rice: Short-grain white rice or brown sushi rice, seasoned with vinegar and sugar
