Ingredients

  • 4 large leeks
  • 2 tablespoons unsalted butter
  • 2 1/4 pounds skinless boneless salmon fillet
  • 1/4 cup chopped fresh dill leaves
  • 1 teaspoon freshly grated lime zest
  • 1 1/2 teaspoons coarse salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 large egg
  • 1 tablespoon water
  • a 17 1/4-ounce package frozen puff pastry sheets (thawed according to package instructions)
  • Sour-Cream Chile Sauce

Method

  • Cut white and pale-green parts of leeks crosswise into 1/2-inch-thick slices.
  • In a bowl of cold water wash leeks well and lift from water into a colander to drain.
  • Pat leeks dry.
  • In a large skillet cook leeks in butter over moderate heat, stirring, until tender, about 12 minutes, and cool.
  • Cut salmon into roughly 3/4-inch pieces and in a bowl toss with leeks, dill, zest, salt, and pepper until combined well.
  • In a small bowl whisk together egg and water to make an egg wash. On a lightly floured surface with a lightly floured rolling pin roll 1 puff pastry sheet into a 10-inch square and the other into a 12-inch square.
  • Transfer 10-inch pastry square to a floured large baking sheet and mound salmon filling in center, forming a round 8 inches in diameter.
  • Brush edges of pastry evenly with some egg wash.
  • Carefully drape remaining pastry square over salmon and gently press edges together to seal.
  • With a sharp knife trim edges of pastry to form a 10-inch round.
  • Crimp edges and cut 4 steam vents on top of crust.
  • Brush crust evenly with some remaining egg wash. Chill pie, loosely covered, at least 1 hour and up to 3.
  • Preheat oven to 400F.
  • Bake pie in middle of oven until pastry is golden brown, about 30 minutes.
  • Serve pie warm or at room temperature with sauce.
