Ingredients

• 2 lbs (sliced) tuna
• 1 tbsp (grated) wasabi
• 1 tbsp sesame oil
• 2 tbsp soy sauce
• 4 cups dashi stock
• 2 (sliced) green onions
• 1/4 cup pickled ginger
• 1 tbsp toasted sesame seeds
• 4 lime wedges

Instructions

1. Step 1: Place 2 lbs of chilled tuna slices in a single layer on a large serving platter, ensuring they are not overlapping to maintain even presentation and texture. Tip: Keep the tuna refrigerated until ready to serve to preserve its freshness and firmness.
2. Step 2: In a small bowl, combine 1 tbsp grated wasabi, 1 tbsp sesame oil, and 2 tbsp soy sauce. Whisk vigorously for 1-2 minutes until the mixture is smooth and emulsified, with no visible streaks of wasabi. Tip: Avoid over-whisking, as this can cause the wasabi to lose its potency and sharpness.
3. Step 3: Pour 4 cups of warm dashi stock into a shallow serving bowl, ensuring the liquid is at a comfortable temperature for drinking but not hot enough to melt the tuna. Arrange 2 sliced green onions diagonally across the platter’s edge, 1/4 cup pickled ginger in a small dish, and 1 tbsp toasted sesame seeds in a separate bowl.
4. Step 4: Garnish the tuna with additional sliced green onions, placing them in small mounds over the fish for visual contrast. Squeeze the juice of 4 lime wedges over the tuna just before serving, ensuring even distribution for a bright, citrusy finish.
5. Step 5: Serve immediately, accompanied by the wasabi-soy sauce, dashi stock, pickled ginger, sesame seeds, and lime wedges, allowing guests to customize their portions with the accompaniments. Tip: For an extra touch, provide small spoons alongside the sauce for easy dipping.
