Seared Tuna with Wasabi-Butter Sauce
  1. 1

    In a small saucepan over medium heat, combine the white wine vinegar, white wine, and shallots. Simmer until the liquid reduces to about 2 tablespoons. Strain out the shallot and discard it, then return the liquid to the pan.

  2. 2

    Stir the wasabi and soy sauce into the reduction in the pan. Over low heat, slowly whisk in the butter, adding one cube at a time and allowing the mixture to emulsify. Do not let the mixture boil. When all the butter is incorporated, stir in the cilantro and remove from the heat. Pour into a small bowl and set aside.

  3. 3

    Heat a large skillet over medium-high heat. Brush the tuna steaks with olive oil and season with salt and pepper. Place them in the hot skillet and sear for 3 to 5 minutes on each side. Do not overcook; the fish should be served still slightly pink in the center. Serve with the sauce.
