Ingredients

  • Heaping 1/4 cup fresh rosemary needles
  • 2 large garlic cloves
  • 1/2 cup extra-virgin olive oil
  • 4 6-ounce skinless halibut fillets (about 1 1/2 inches thick) or any other mild white fish, such as branzino or striped bass
  • 1 1/2 cups veal stock (see Veal Breast Stracotto, page 235) or any quality veal or beef stock
  • 1/4 cup green peppercorns, soaked in water for 1 hour
  • 1 1/4 teaspoons fresh lemon juice
  • Kosher salt
  • 8 large outer leaves of butter lettuce or Boston lettuce

Method

  • Adjust the oven rack to the middle position and preheat the oven to 350F.
  • Combine the rosemary, garlic, and 1/4 cup of the olive oil in the bowl of a miniature food processor or the jar of a blender and puree.
  • Rinse the fish fillets, pat them dry with paper towels, and lay them in a single layer in a nonreactive baking dish.
  • Pour the marinade over the fish and turn to coat with the marinade on all sides.
  • Combine the veal stock and peppercorns in a medium saute pan over high heat.
  • Bring the stock to a boil and continue to boil until it is glossy and has reduced by two-thirds, about 10 minutes.
  • You want the liquid to be shiny and translucent with the consistency of a thick glaze or thin gravy.
  • If you cook it for so long that it becomes dull and gravy-like, stir in enough water to obtain the desired consistency.
  • Turn off the heat while you cook the fish.
  • Just before serving, if the sauce has cooled, warm it over medium heat.
  • Stir in the lemon juice just before serving.
  • Remove the fish fillets from the marinade and season on both sides with salt.
  • Heat the remaining 1/4 cup of olive oil in a large nonstick saute pan over medium-high heat until the oil is almost smoking and slides easily in the pan, 2 to 3 minutes.
  • Place the fillets skin side down in the pan and cook for 1 to 2 minutes so the skin begins to brown and crisp.
  • Place the pan in the oven and cook the fish for about 4 minutes, until the skin is golden brown.
  • To check for doneness, look at the skin around the outer edges of the fish; you want it to be a rich, crunchy, french-fry brown around the sides.
  • Remove the pan from the oven and slide a spatula under each fillet to turn it, taking care not to tear the skin or to burn yourself, as the pan will be searing hot.
  • Return the pan to the oven and cook the fish for another minute.
  • Remove the pan from the oven and remove the fish to a plate or cutting board.
  • Line a plate with paper towels.
  • Without wiping out the pan, place it over high heat and, working in batches, place the lettuce leaves in the pan for 30 seconds to 1 minute to wilt them slightly.
  • Remove the leaves to a paper towel and use another paper towel to gently pat them dry.
  • Drape two lettuce leaves in the center of each of four large plates, overlapping them slightly.
  • Lay the fish on the lettuce and spoon the sauce, including the peppercorns, over the fish, dividing it evenly.
