Ingredients

Main Ingredients

  • ½ cup cold heavy cream
  • 1 teaspoon pure vanilla extract
  • 4 large egg yolks
  • 1 tablespoon unsalted butter, at room temperature
  • ¼ cup brewed espresso or strong coffee, at room temperature
  • 3 tablespoons granulated sugar, divided
  • ⅛ teaspoon sea salt
  • 8 ounces good quality bittersweet or semi-sweet chocolate, chopped (Ghirardelli 60% bittersweet recommended)
  • 4 large egg whites

For Garnish

  • Sweetened whipped cream
  • Chocolate shavings
  • Fresh strawberries or raspberries

Instructions

  1. Whip Cream: Using an electric mixer, beat the cold heavy cream with vanilla extract until stiff peaks form. Cover and chill in the refrigerator to keep it cold and ready for folding later.
  2. Prepare Egg Yolk Mixture: In a large metal bowl, combine egg yolks, room-temperature unsalted butter, cooled espresso, 2 tablespoons of sugar, and sea salt. Place the bowl over a saucepan of gently simmering water, ensuring the bowl does not touch the water. Whisk constantly and cook until the mixture lightens in color, becomes frothy, and nearly doubles in volume. Use an instant-read thermometer to confirm the temperature reaches 160°F. This gentle heating ensures safety and thickens the mixture, taking about 1-5 minutes depending on heat and equipment.
  3. Melt Chocolate: Remove the bowl from the heat and add chopped bittersweet chocolate. Whisk until the chocolate completely melts and the mixture is smooth. Allow it to cool to room temperature, whisking occasionally to maintain smoothness and prevent crusting.
  4. Beat Egg Whites: In a separate medium bowl, beat egg whites on medium speed with an electric mixer until foamy. Gradually add the remaining 1 tablespoon of sugar while mixer is running. Increase the speed to high and continue to beat until firm peaks form, giving the mousse its light and airy texture.
  5. Combine Mixtures: Gently fold the beaten egg whites into the chocolate mixture in two additions to retain airiness. Then, fold in the whipped cream carefully until just evenly blended, taking care not to overmix and deflate the mousse.
  6. Chill the Mousse: Divide the chocolate mousse evenly into six 6 to 8-ounce ramekins or cups. Chill in the refrigerator for at least 2 hours until set and firm. The mousse can be prepared a day in advance for convenience.
  7. Serve and Garnish: Before serving, allow the mousse to sit at room temperature for about 10 minutes for optimal texture. Top each cup with a dollop of sweetened whipped cream, chocolate shavings, and fresh strawberries or raspberries to enhance flavor and presentation.

Notes

  • Ensure the egg yolk mixture reaches 160°F to safely cook the eggs.
  • Use good quality bittersweet chocolate for best flavor and texture.
  • Fold mixtures gently to maintain mousse's light and airy texture.
  • The mousse can be made one day ahead and kept chilled until ready to serve.
  • Allow mousse to warm slightly at room temperature before serving for a smoother mouthfeel.
  • Espresso can be substituted with strong coffee if espresso is unavailable, without compromising flavor.
