Classic Maguro Don (Japanese Tuna Rice Bowl)
Experience the pristine flavors of raw tuna belly with this classic Maguro Don. Perfectly sliced sashimi rests over a bed of warm rice, accented with freshly grated wasabi and elegant cucumber garnishes.
Maguro Don, or tuna rice bowl, is a celebration of minimalism and ingredient quality in Japanese cuisine. By sourcing the freshest tuna belly and pairing it with real grated wasabi, this dish transforms simple components into a luxurious culinary experience. The traditional shark-skin grated wasabi adds a bright, floral heat that perfectly cuts through the rich fattiness of the tuna.
Ingredients
- 300 g sashimi-grade raw tuna belly
- 2 cups cooked sushi rice
- 1 piece fresh wasabi root
- 1/2 cucumber
- to taste soy sauce
Instructions
- 1Portion the tuna block

Begin by taking the large block of raw tuna belly and making an initial cut down the center. Use a long, sharp slicing knife to cleanly separate the meat into smaller, manageable rectangular segments for easier handling.
Tip: Ensure your knife is extremely sharp to avoid tearing the delicate muscle fibers of the tuna. - 2Segment the tuna

Take the trimmed section of the tuna belly and carefully slice it lengthwise. Make smooth, even cuts to create thick, uniform rectangular strips of tuna, preparing them for the final sashimi cuts.
Tip: Wipe the blade of your knife with a damp cloth between cuts to maintain a clean edge and prevent the fish from sticking. - 3Slice into sashimi pieces

Place a rectangular strip of tuna on a dark cutting board. Angle your knife slightly and pull it smoothly through the flesh in a single motion to cut the block into beautiful, thick sashimi-sized pieces.
Tip: Cut against the grain of the fish to yield the most tender pieces. - 4Grate the wasabi

Take the peeled fresh wasabi root and grate it against the shark-skin grater in a circular motion. This traditional method produces a fine, pasty consistency that maximizes the wasabis natural spice and vibrant color.
Tip: Work in small, circular motions for the best texture. Freshly grated wasabi loses its potency quickly, so prepare it just before serving. - 5Prepare the cucumber garnish

Take a fresh section of cucumber and slice it diagonally. Using precise knife work, score the cucumber into thin, connected layers so it can be fanned out into an elegant, decorative shape to accent the final bowl.
Tip: Keep the cuts thin and uniform so the cucumber fans out beautifully without snapping.
