Servings

Ingredients for 4

  • Mousse
  • 200 g single-origin dark chocolate (70% cocoa) , finely chopped
  • 50 g unsalted butter , cubed
  • 4 free-range eggs , separated
  • 50 g golden caster sugar
  • 30 ml brewed espresso , cooled
  • 20 ml Cognac
  • 1 pinch flaky sea salt
  • To serve
  • 100 ml double cream , lightly whipped
  • cocoa nibs , to garnish

Method

  1. Melt the chocolate and butter gently over a bain-marie until glossy, then stir in the espresso and Cognac and remove from the heat.
  2. Beat in the egg yolks one at a time until the mixture is thick and shiny, then leave to cool to room temperature.
  3. Whisk the egg whites with the salt to soft peaks, adding the sugar gradually to form a firm, glossy meringue.
  4. Fold a third of the meringue into the chocolate to loosen, then gently fold in the rest in two further additions.
  5. Pipe or spoon into serving glasses and chill for at least 6 hours to set fully.
  6. Top with a quenelle of softly whipped cream, a scatter of cocoa nibs and a few flakes of sea salt to serve.
