This is by far the prettiest thing I’ve ever made

Ingredients

• 2 cups Sushi Rice (short‑grain Japanese rice, rinsed until water runs clear)
• 3 tablespoons Rice Vinegar (seasoned with sugar and salt)
• 1 tablespoon Granulated Sugar (helps balance the vinegar)
• 1 teaspoon Salt (fine sea salt)
• 4 ounces Tuna (sashimi grade) (cut into small cubes)
• 4 ounces Salmon (sashimi grade) (cut into small cubes)
• 0.5 medium Cucumber (peeled, seeded, diced)
• 1 ripe Avocado (diced, tossed with lime juice to prevent browning)
• 1 teaspoon Lime Juice (prevents avocado from oxidizing)
• 2 tablespoons Soy Sauce (for drizzling)
• 1 tablespoon Pickled Ginger (optional garnish)
• 1 teaspoon Sesame Seeds (toasted)
• 1 teaspoon Wasabi Paste (optional, for a kick)
• 1 spray Neutral Oil Spray (for greasing waffle maker)

Instructions

1. Rinse the Rice

   Place the sushi rice in a fine‑mesh sieve and rinse under cold running water until the water runs clear, about 5 minutes.

   Time: PT5M

2. Cook the Rice

   Transfer the rinsed rice to the rice cooker, add the appropriate amount of water (usually 1 cup rice to 1 ¼ cups water), and start the cooker. Let it cook undisturbed for about 20 minutes until fluffy.

   Time: PT20M

3. Prepare Sushi Vinegar

   In a small bowl combine rice vinegar, granulated sugar, and salt. Stir until the sugar and salt dissolve completely.

   Time: PT5M

4. Season the Rice

   Transfer the hot rice to a large mixing bowl, gently fold in the sushi vinegar mixture using a spatula. Spread the rice out to cool to room temperature, about 10 minutes.

   Time: PT10M

5. Preheat the Waffle Maker

   Plug in the waffle maker and set it to medium‑high heat (approximately 190°C). Allow it to preheat for 3 minutes.

   Time: PT3M

   Temperature: 190°C

6. Crisp the Rice

   Lightly spray the waffle plates with neutral oil. Spoon about ¼ cup of seasoned rice onto each compartment, spreading it thinly. Close the lid and cook for 3–4 minutes until the rice is golden and crisp.

   Time: PT5M

   Temperature: 190°C

7. Cool the Crispy Squares

   Using a spatula, carefully remove the crispy rice squares and place them on a wire rack for 2 minutes to firm up.

   Time: PT2M

8. Prepare Toppings

   Dice the tuna and salmon into uniform ½‑inch cubes. Peel, seed, and dice the cucumber. Dice the avocado and toss gently with lime juice to prevent browning.

   Time: PT10M

9. Assemble the Mosaic

   Arrange the crispy rice squares on a serving plate in a grid. Artistically place tuna, salmon, cucumber, and avocado cubes on each square, creating a colorful pattern. Drizzle soy sauce, sprinkle toasted sesame seeds, and add small dollops of pickled ginger and wasabi as garnish.

   Time: PT5M

10. Serve Immediately

    Present the sushi mosaic while the rice is still crisp. Enjoy with extra soy sauce or a side of miso soup if desired.

    Time: PT0M

Troubleshooting

Storage

Refrigerator: Store leftover seasoned rice and uncooked toppings separately in airtight containers for up to 2 days. Re‑crisp rice in the waffle maker before serving.

Freezer: Uncooked seasoned rice can be frozen in a zip‑top bag for up to 1 month. Thaw in the refrigerator before re‑crisping. Do not freeze raw fish after it has been diced.

Room temperature: Do not leave assembled sushi mosaic at room temperature for more than 2 hours due to food safety concerns.

Make-Ahead Tips

• Cook and season the sushi rice up to step 4 and store it covered in the refrigerator for up to 24 hours.
• Dice the fish and vegetables and keep them chilled in separate containers; assemble just before serving for maximum crispness.
