A classic chocolate mousse recipe that transforms simple ingredients into a luxurious dessert, evoking childhood memories and special family gatherings.

Ingredients

Scale
  • 4 large eggs, separated
  • 150 grams caster sugar
  • 3 tablespoons orange liqueur
  • 170 grams high-quality bittersweet chocolate (70%-74% cocoa), chopped
  • 1 ½ teaspoons espresso powder
  • 60 ml hot water
  • 170 grams unsalted butter, softened
  • 1 teaspoon kosher salt
  • 12 grams granulated sugar
  • 238 grams heavy cream
  • 1 teaspoon vanilla paste
  • Flaky sea salt (optional, for topping)

Instructions

  1. Set up a double boiler using two medium heatproof bowls over a medium saucepan filled with a couple of inches of water.
  2. Fill a large bowl with cold water and ice cubes for the ice bath.
  3. In a medium bowl, whisk the egg yolks and 150 grams of caster sugar for about 3-4 minutes until thickened.
  4. Add 3 tablespoons of orange liqueur and place the bowl over the simmering water, whisking until heated (3-8 minutes).
  5. Remove from heat and set the bowl into the ice bath, whisking until cooled to room temperature.
  6. In a separate bowl, melt the chocolate with the espresso powder and hot water over the double boiler, stirring until smooth.
  7. Incorporate the softened butter into the melted chocolate until fully melted.
  8. Slowly whisk the chocolate mixture into the cooled egg yolk mixture until combined.
  9. In a clean bowl, beat the egg whites with 1 teaspoon of kosher salt until soft peaks form, then gradually add 12 grams of granulated sugar until stiff peaks form.
  10. Fold a quarter of the egg whites into the chocolate mixture, then gently fold in the remaining egg whites until just combined.
  11. Spoon the mousse into serving bowls and refrigerate for at least 4 hours, ideally overnight.
  12. Before serving, whisk the heavy cream with vanilla paste until stiff peaks form.
  13. Serve the mousse topped with a sprinkle of flaky sea salt or a dollop of Chantilly cream.

Notes

Ensure your bowls and beaters are grease-free for optimal egg white aeration. Use high-quality chocolate for the best flavor.
