Fresh Wasabi and Organic Soy Marinated Blue Fin Tuna with Tonburi and Yuzu
For Fatty Tuna:
Combine the wasabi, soy sauce, hijiki and shiso, and mix well. Gently fold the diced tuna into the mixture, allowing it to marinate for 3-5 minutes.
For Red Radish:
Combine all ingredients and mix well. Set aside.
For Yuzu Mirin Reduction:
Reduce the mirin in a sauce pan over low-medium heat down to ¼ cup. Add the dashi and reduce again to ¼ cup. Stir in the yuzu and soy, and allow the mixture to chill.
For Yuzu Gelée:
Place gelatin in the water. In a saucepan over low heat, dissolve the gelatin. Add the sugar and yuzu juice, and mix well. Pass the mixture through a fine sieve, and pour it into a 10-inch by 13-inch glass baking pan. Allow gelée to cool and harden a bit. Dice it into 1/8-inch squares; chill and reserve.
To Assemble and Serve:
Place a dollop of the red radish mixture in the center of each serving plate. Divide half of the marinated fatty tuna among the plates. Layer some pickled ginger on the tuna and then place the remaining tuna on top. Place the diced yuzu gelée and 2 teaspoons of tobiko wasabi on each plate around the tuna. Top the tuna with ¾ Tablespoon tonburi on each plate. Drizzle some yuzu mirin reduction around each plate. Garnish with 5 shiso sprouts per plate.
