directions

Prepare the Tuna Mosaic:
Mix the diced sushi-grade tuna with soy sauce and sesame oil. On a flat surface or cutting board, alternate small portions of sushi tuna and canned tuna in a checkerboard layout. Gently press into a square or rectangle shape. Wrap the sides with a halved sheet of nori to help maintain the structure. Sprinkle with black and white sesame seeds.
Make the Rice Base:
While the rice is still warm, mix it with furikake seasoning and rice vinegar. Spoon the rice into shallow bowls, gently shaping a slight indentation in the center to hold the tuna mosaic.
Toss the Salad:
In a bowl, combine the sliced radishes, halved cherry tomatoes, and chopped herbs. Drizzle with olive oil and vinegar or lemon juice. Season with salt and black pepper to taste. Let the salad sit for a few minutes to allow the flavors to meld.
Assemble the Bowl:
Carefully place the prepared tuna mosaic atop the center of the rice. Arrange the radish and tomato salad on the side. Garnish with additional sesame seeds or crispy shallots if desired. Serve immediately.

This dish is best served fresh due to the raw fish and the delicate texture of the mosaic arrangement. However, if needed, components can be stored separately:

Rice: Store in an airtight container in the refrigerator for up to 2 days. Reheat gently in the microwave with a damp paper towel to retain moisture.

Assemble just before serving for best presentation and texture.

FAQs

Can I use only canned tuna instead of sushi-grade tuna?

Yes, you can use just canned tuna, though the visual mosaic and texture will differ slightly. Consider mixing with a bit of mayonnaise or miso for added richness.

Is this dish safe to eat with raw tuna?

Yes, provided that you use sushi-grade tuna from a trusted source. Keep it refrigerated and consume the same day.

Can I prepare the components in advance?

You can prep the rice and salad in advance, but the tuna mosaic should be assembled just before serving for the best texture and appearance.

What is furikake and where can I find it?

Furikake is a Japanese seasoning made from seaweed, sesame seeds, and dried fish. It’s available in Asian grocery stores or online.

Can I make this bowl vegetarian?

Yes, replace the tuna with marinated tofu or tempeh and use vegetarian furikake or omit it entirely.

What kind of rice works best for the base?

Short-grain or multigrain rice with a slightly sticky texture works well to support the mosaic and hold its shape.

How do I cut the tuna into uniform shapes?

Use a sharp knife and chill the tuna beforehand. Dice it into evenly sized cubes for the best checkerboard effect.

Can I add sauces to the bowl?

A drizzle of ponzu sauce or a soy-sesame dressing can enhance flavor without overpowering the dish.

Is purple rice healthier than white rice?

Purple rice typically contains more antioxidants and fiber compared to white rice, making it a nutritious choice.

What garnishes pair well with this dish?

Try crispy shallots, microgreens, or a few drops of chili oil for extra flavor and presentation.
