Servings: Serves 6
Season all sides of the tuna block with salt and pepper. Sprinkle all sides with sesame seeds. Heat the olive oil in a nonstick skillet over medium-high heat. When the pan is hot, quickly sear the tuna on all sides, about a minute per side. Remove from the pan and refrigerate immediately. Cut into 6 pieces.
For Wasabi Whipped Cream
Combine the wasabi paste and whipping cream in a medium mixing bowl, and whisk thoroughly.
Paint some of the soy sauce on each serving plate. Set a block of the tuna onto the sauce. Garnish with chopped pickled ginger and wasabi whipped cream.
