  • Easy

Check out this showstopper recipe for zesty lemon mousse with lemon and pink pepper shortbread. This dessert is easy to make and an impressive way to end your dinner party. Native to South America, pink pepper is an entirely different plant to black/green/white pepper, which all come from the same vine, piper nigrum. Pink peppercorns have an almost citrussy zing to them and they pair brilliantly with this lemon-scented recipe




  • soft butter 90g
  • caster sugar 50g
  • lemon 1/2, zested
  • plain flour 75g
  • cornflour 25g
  • pink peppercorns 2 tsp, roughly crushed


  • caster sugar 250g
  • lemons 3 1/2 large, zested and juiced
  • eggs 3, separated
  • gelatin 4 sheets, we use Dr Oetker platinum grade, 2g per sheet
  • double cream 300ml


  • Step 1

    For the shortbread, put the butter in a mixing bowl and beat together with the sugar.

  • Step 2

    Add the lemon zest and mix well.

  • Step 3

    Add the plain flour, cornflour, peppercorns and a pinch of salt, and stir until it comes together as a soft dough.

  • Step 4

    Shape into a 10cm sausage and wrap in clingfilm. Put in the freezer.

  • Step 5

    For the mousse, put the sugar in a small saucepan with the zest.

  • Step 6

    Squeeze the juice from the lemons, plus the ½ from the shortbread, into a jug, then top up with cold water to give you 300ml of liquid.

  • Step 7

    Pour into the pan and, over a medium heat, stir until the sugar melts.

  • Step 8

    Add the egg yolks and whisk for 5 minutes, keeping just below boiling point. Pour into a large dish to cool slightly.

  • Step 9

    Soak the gelatine sheets in cold water for 10 minutes.

  • Step 10

    Once the lemon mixture has cooled to warm, remove the gelatine from the water and squeeze.

  • Step 11

    Add to the lemon mixture, stirring until dissolved.

  • Step 12

    Loosely cover with clingfilm and leave to cool.

  • Step 13

    Put the egg whites in a clean mixing bowl and whisk to stiff peaks.

  • Step 14

    Put the cream in a second mixing bowl and whisk to soft peaks, then add the lemon mixture to this, a third at a time, and continue whisking.

  • Step 15

    Use a large metal spoon to fold the egg whites through the lemony cream, mixing until just incorporated.

  • Step 16

    Pour into 8 glasses and chill in the fridge for at least 2 hours.

  • Step 17

    Heat the oven to 170C/fan 150C/gas 3½. Remove the shortbread dough from the freezer.

  • Step 18

    Unwrap and cut into 5mm discs, spacing generously over 2 lined baking sheets. Cook for 15 minutes or until golden.

  • Step 19

    Serve the mousse with the biscuits.
