Ingredients

• 4 sheets dashi kombu, such as Shirakiku
• 3 fresh shiso leaves
• 1/2 fresh mango
• 3 ounces halibut
• Sea salt
• 1 sheet dashi kombu, such as Shirakiku, softened with a damp cloth
• 5 teaspoons ponzu sauce
• White truffle oil, for serving
• Wasabi tobiko, for serving
• Black caviar, for serving

Instructions

1. For the mango salsa: Slice the dashi kombu and shiso leaves as thinly as possible. Dice the mango into small cubes. Toss the dashi kombu, shiso leaves and mango together on a cutting board and chop as finely as possible to combine. Set aside.
2. For the halibut crudo: Sprinkle the halibut with sea salt, wrap in the dashi kombu and refrigerate for 30 minutes to marinate.
3. Slice the halibut into 5 thin pieces the size of sushi nigiri (about 2 inches long and less than 1/2 inch thick). Place 5 dots of ponzu sauce (about 1 teaspoon each) on a plate. Roll the halibut slices and stand them on their side on the dots of ponzu. Add 2 drops of the white truffle oil and about 1/2 teaspoon mango salsa to each piece of halibut. Then add a small dollop (1/2 teaspoon or less) of the wasabi tobiko and an even smaller dollop of the black caviar to each piece of halibut. Serve.
