Method

  • In a mixing bowl, combine the first 10 ingredients together.
  • Mix well.
  • In a small bowl, whisk the mustard with 1 1/2 tablespoons warm water until a paste forms.
  • Gradually whisk in the soy sauce.
  • Set aside.
  • In a saucepan, boil the wine, vinegar, shallot and peppercorns, until almost no liquid remains in the pan, about 2 minutes.
  • Add the cream and boil until slightly thickened, about 1 minute.
  • Season with salt and pepper.
  • Set the sauce aside.
  • In a mixing bowl, whisk the flour, water and egg together.
  • Season with salt and pepper.
  • Set aside.
  • Season the ahi with salt.
  • Spread the wasabi evenly over 4 nori half-sheets.
  • Place 1 piece of the ahi one end of each nori sheet.
  • Fold the nori over the ahi to cover (the ends will be exposed).
  • In a medium-saucepan, heat the oil.
  • Dip 1 ahi roll in the soy sauce and then in the flour; shaking off any excess flour.
  • Dip the rolls in the tempura batter and fry in the oil until the outside is crispy and the tuna is rare inside, about 40 seconds.
  • Remove the ahi from the oil and drain on a paper-lined plate.
  • Season with salt and pepper.
  • Repeat the remaining rolls.
  • Bring the reduction sauce to a simmer.
  • Whisk in enough mustard to desired taste.
  • Whisk in the butter.
  • To assemble, spoon the sauce in the center of the plate.
  • Pile the relish in the center of the sauce.
  • Slice the tempura ahi and lay them directly on top of the relish.
  • Garnish with parsley
