How to Make Chocolate Mousse

Ingredients You’ll Need

4 Large Eggs, Separated: Eggs are the unsung heroes of this mousse, providing structure, richness, and that characteristic airy texture. Separating the eggs is essential. The yolks contribute to the creamy richness and emulsification, while the whites, when whipped, create the light and airy volume that defines mousse.

Choosing Your Eggs: Opt for fresh, large eggs. If you’re concerned about using raw eggs, ensure they are pasteurized. Room temperature eggs are generally recommended for better volume when whipping egg whites, but for this recipe, starting with cold eggs for separation and then allowing the whites to come closer to room temperature before whipping can be beneficial.

150 grams Caster Sugar: Caster sugar, also known as superfine sugar, is granulated sugar that is ground more finely. It dissolves more easily into the egg yolks, creating a smoother base for the mousse.

3 Tablespoons Orange Liqueur: The subtle orange liqueur adds a layer of complexity and brightness that elevates the chocolate mousse from simply delicious to truly exceptional.

170 grams High-Quality Bittersweet Chocolate, 70% – 74% Cocoa | Chopped: The star of the show! The quality of your chocolate will directly impact the final taste of the mousse.

1 ½ teaspoons Espresso Powder: Espresso powder is a secret weapon in chocolate desserts. It enhances and intensifies the chocolate’s richness, depth, and complexity.

60 ml Hot Water: Hot water is used to melt the chocolate and espresso powder together, creating a smooth ganache-like base.

170 grams Unsalted Butter, Cut into ½-inch Cubes and Softened to Room Temperature: Butter adds richness, smoothness, and a luxurious mouthfeel to the mousse.

1 teaspoon Diamond-Crystal Kosher Salt: Salt is crucial in desserts, balancing sweetness and enhancing flavors.

12 grams Granulated Sugar: A small amount of granulated sugar is added to the egg whites to help stabilize them and create a glossy meringue.

238 grams Heavy Cream: Heavy cream is essential for making stable and luscious whipped cream.

1 teaspoon Vanilla Paste: Vanilla paste adds a concentrated vanilla flavor and is optional but highly recommended.

Step-by-Step Directions

Prepare a double boiler by placing two medium heatproof bowls over a lightly simmering pot of water. Make sure the bowls do not touch the water.

In one bowl, whisk together the egg yolks and caster sugar until foamy. Heat this bowl over the simmering water for about 3–8 minutes, whisking constantly until the mixture thickens.

Remove from heat and cool quickly by placing the bowl in a larger bowl filled with ice water. Stir until the mixture returns to room temperature.

In another bowl, melt the chopped chocolate and espresso powder with the hot water over the simmering pot. Stir until smooth, then remove from heat.

Mix the melted chocolate into the cooled egg yolk mixture until combined.

In a clean bowl, beat the egg whites and kosher salt until soft peaks form. Gradually add the granulated sugar and continue beating until stiff peaks form.

Fold a quarter of the egg whites into the chocolate mixture to lighten it. Then gently fold in the remaining egg whites in two additions.

Transfer the mousse to serving dishes and cover with plastic wrap. Chill in the fridge for at least 4 hours or overnight.

Before serving, you can whip the heavy cream and vanilla paste until stiff peaks form. Top the mousse with the whipped cream and enjoy!

How to Serve Chocolate Mousse

Spoon or pipe the chilled mousse into individual serving dishes. Feel free to garnish with a sprinkle of flaky sea salt or a dollop of whipped cream for an extra touch of elegance.

How to Store Chocolate Mousse

Store any leftover mousse in the refrigerator, tightly covered with plastic wrap. It should last for up to three days. Just remember to garnish it fresh when serving.

Tips for the Best Chocolate Mousse

Use high-quality chocolate for the best flavor. Be gentle when folding in the egg whites to keep the mousse light and airy. Chill the mousse for at least four hours to ensure it sets properly.

Recipe Variations

For a different flavor, try adding a splash of raspberry or mint extract in place of the orange liqueur. You can also top the mousse with fresh berries for added freshness.
