Prepare the Cookie Crunch Base

Make the Chocolate Mousse

  • Melt the dark chocolate in a heatproof bowl over simmering water, stirring until smooth. Set aside to cool slightly.
  • In a separate bowl, beat the egg yolks with 75g of sugar until pale and creamy. Add the melted chocolate and mix until well combined.
  • In another bowl, whip the cream until stiff peaks form. Gently fold the whipped cream into the chocolate mixture.
  • Finally, beat the egg whites and remaining sugar until soft peaks form. Carefully fold them into the chocolate mixture to keep it airy.
  • Spoon the mousse into the prepared molds, covering the cookie base. Chill for at least 1 hour.

Prepare the Lemon Mousse

  • In a saucepan, whisk together the lemon juice, zest, egg yolks, and sugar over low heat, whisking continuously until thickened.
  • Bloom the gelatin in cold water, then stir it into the warm lemon mixture until dissolved. Let it cool.
  • Whip the cream until soft peaks form and fold into the lemon mixture gently.
  • After the chocolate mousse has set, top it with the lemon mousse. Return it to the fridge to set for another hour.
