Chef Adam Byatt's simple recipe makes for an impressive dinner party dish.


  1. For the parsley mayonnaise, blend the parsley and vegetable oil in a blender until smooth. (This will take 1-2 minutes.)

  2. Blend the egg yolks, vinegar and mustard in a food processor until well combined. With the motor running, slowly add the parsley oil to form a thick mayonnaise.

  3. Season with salt, freshly ground black pepper and a squeeze of lemon juice.

  4. For the walnut truffle pesto, heat the olive oil and walnuts in a frying pan over a medium heat for 4-5 minutes, or until golden brown. Set aside to cool.

  5. Blend the cooled walnuts and olive oil, thyme, garlic, truffle, parmesan and white truffle oil in a food processor until smooth.

  6. For the seabass, preheat the oven to 200C/400F/Gas 6 and place a large oven tray in the oven. Cut out four 10cm/4in squares of greaseproof paper.

  7. Slice the seabass fillets at an angle into 0.5cm/¼in thick slices. Divide the slices between the squares of greaseproof paper, overlapping each slice slightly.

  8. Season with salt and lemon zest and drizzle over the olive oil.

  9. Place the sea bass slices onto the preheated baking tray and roast for 2-3 minutes.

  10. Drain the endive leaves, pat dry and toss with some of the truffle pesto.

  11. To serve, place the seabass into the centre of serving plates and drizzle a little parsley mayonnaise over the top. Arrange the endive leaves around the edge and scatter over the parsley cress.
