Method

  • For the sauce, line a sieve with cheesecloth and place over a bowl.

  • Whisk in the remaining ingredients and set aside.
  • For the sole, roll up each piece of sole lengthwise and secure with a toothpick.
  • Place the celery juice in a large saucepan and bring to a simmer.
  • Adjust the heat so that the liquid is at a slow simmer.
  • Add the sole fillets and poach until cooked through, about 8 minutes.
  • Carefully remove the fillets from the liquid.
  • Toss together the garnish ingredients.
  • Spoon some of the sauce in the center of each of 4 plates.
  • Remove the toothpicks from the sole fillets and place 2 of the rolls over the sauce on each plate.
