Ingredients

  • 1 lemon, zest of, finely grated
  • 1 lime, zest of, finely grated
  • 1 small onion, roughly chopped
  • 1 leek, green part trimmed, cut into chunks
  • 2 bunches fresh dill, leaves picked
  • 2 14 lbs side fresh salmon, skin left on
  • 2 ounces superfine sugar
  • 3 tablespoons white wine vinegar
  • 1 teaspoon white wine vinegar
  • 12 cup water
  • 1 large fennel bulb
  • lemon juice
  • 1 pinch salt
  • 3 tablespoons Dijon mustard

Method

  • Put the lemon and lime zest, onion, leek and a small handful of the dill in a food processor and whiz to a smooth paste.
  • Spread the paste evenly over the salmon - this marinade will partially cook the salmon and help draw out any moisture.
  • Cover with plastic wrap place a couple of food cans or heavy weights in a large dish and use to weigh down the salmon and encourage the flavours to penetrate.
  • Chill for 24 hours.
  • Heat the sugar, white wine vinegar and water in a small saucepan until the sugar has dissolved.
  • Meanwhile, thinly slice the fennel.
  • Put in a bowl and toss with a squeeze of lemon juice and a pinch of salt.
  • Toss with a small handful of the dill, then pour over the hot vinegar syrup.
  • Set aside until completely cool.
  • Rinse the salmon and pat dry with kitchen paper.
  • Spread the cut side evenly with the mustard.
  • Sprinkle over the remaining dill, pressing it into the mustard to coat.
  • Working from the tail end and using a sharp knife with a narrow flexible blade, slice the salmon very thinly - you should be able to see the blade of the knife through the flesh.
  • Arrange the slices on a serving plate.
  • Strain the juices from the fennel, and pile into the centre of the plate.
