Ingredients
- 1 bowl seasoned sushi rice
- 50 g sashimi-grade tuna (maguro)
- 50 g sashimi-grade yellowtail (hamachi)
- 3-4 pieces sashimi-grade scallops
- 30 g fresh sea urchin (uni)
- 2 tbsp salmon roe (ikura)
- 1 tsp freshly grated wasabi
- to taste soy sauce
Instructions
- 1Cube the Sashimi

Slice fresh blocks of sashimi-grade tuna and yellowtail into small, uniform cubes. Consistency is key here to ensure every bite has a balanced texture and looks visually striking.
Tip: Chill the fish thoroughly before slicing to make the flesh firmer and easier to cut into precise, clean cubes. - 2Arrange the Seafood Base

Carefully place the cubed tuna, yellowtail, and scallops over a bowl of seasoned sushi rice. Using the side of your knife helps guide the delicate pieces into place for a beautiful and organized presentation.
Tip: Spread the seafood out evenly so every bite of rice is accompanied by a balanced variety of fish. - 3Crown with Fresh Uni

Use a small spoon to gently scoop fresh, bright orange sea urchin from its wooden box. Place it carefully in the center of the bowl on top of the other seafood. The sea urchin adds a rich, buttery sweetness that is essential to the dish.
Tip: Handle the sea urchin very gently as it is extremely delicate and can break apart easily. - 4Top with Glistening Ikura

Spoon glistening orange salmon roe over the sea urchin and seafood. These pearls add a refreshing burst of salty flavor that perfectly complements the richness of the fish and the seasoned rice.
Tip: For the best visual impact, pile the roe centrally to create a vibrant peak of color on top of the bowl. - 5Grate the Fresh Wasabi

Complete the bowl by grating a piece of fresh green wasabi root in a circular motion on a traditional wooden grater. This creates a smooth paste with a clean, spicy kick that far surpasses the flavor of pre-packaged alternatives.
Tip: Grate the wasabi immediately before serving to maintain its potent aroma and signature sharp flavor.
