What is Chocolate Mousse?
Chocolate mousse has a storied history, tracing back to 18th century France when it was a luxurious dish enjoyed by the elite. Its name means "foam" in French, an apt description of its light, airy consistency created through whipped egg whites and cream. The traditional chocolate mousse features bittersweet chocolate at its core, resulting in a dessert that balances rich chocolate flavor with a light texture.
The beauty of our chocolate mousse lies in its delightful contrast; it’s both creamy yet ethereal, providing bursts of intense chocolate that are brightened by the added liqueur. This dessert is incredibly versatile, making it perfect for holidays, celebrations, or simply as a sumptuous weeknight treat. Each bite transports you to a little slice of heaven, blending nostalgia with gourmet allure.

Ingredients
4 Large Eggs, Separated: The unsung heroes of this mousse, providing both structure and richness. Use fresh, large eggs for best results. If you’re concerned about using raw eggs, opt for pasteurized eggs.
150 grams Caster Sugar: This finely ground sugar dissolves easily into the egg yolks and helps create a smooth base for the mousse. If you don’t have caster sugar, pulse granulated sugar until finer, but don’t overdo it!
3 Tablespoons Orange Liqueur: Elevates the mousse with a hint of citrus complexity. Use good quality brands like Grand Marnier or Cointreau for the best flavor.
170 grams High-Quality Bittersweet Chocolate (70-74% Cocoa): The star of the show! Look for brands like Valrhona or Lindt for a chocolatey depth that’s truly divine.
1 ½ teaspoons Espresso Powder: Enhances the chocolate flavor without overwhelming it. If you lack this ingredient, you can omit it, but you’ll miss out on a new level of richness.
60 ml Hot Water: Helps bloom the espresso powder and create a smooth chocolate mixture.
170 grams Unsalted Butter: Adds luxurious creaminess. Make sure it’s softened to room temperature before using.
1 teaspoon Diamond-Crystal Kosher Salt: Balances the sweetness and enhances the overall flavor profile.
12 grams Granulated Sugar: A small amount added to the egg whites helps stabilize them for that perfect meringue.
238 grams Heavy Cream: Essential for whipping up a luscious, stable whipped cream.
1 teaspoon Vanilla Paste: For an added depth of vanilla flavor, or you can use high-quality vanilla extract.
Flaky Sea Salt (Optional, for Topping): A light sprinkle on top enhances chocolate flavors beautifully.
Step-by-Step Instructions
Prepare Your Double Boiler: Set up a double boiler with two heatproof bowls placed over a medium saucepot filled with two inches of simmering water. The bowls shouldn’t touch the water—this ensures gentle heating.
Ice Bath Ready: Fill a large bowl with cold water and ice cubes. This will be essential for cooling the egg yolk mixture quickly.
Whisk Egg Yolks: In a medium bowl, whisk together the 4 egg yolks with 150 grams of caster sugar until creamy and light, about 3-4 minutes.
Heat the Mixture: Add 3 tablespoons of orange liqueur into the yolk mixture. Place this bowl over the simmering water, whisking continuously for 3-8 minutes until it’s foamy and hot (but not boiling), about 178℉/81℃.
Cool Down: Off the heat, immediately transfer the bowl to your ice bath, whisking until it cools back to room temperature and thickens.
Melt Chocolate: In another bowl, combine 170 grams of chopped bittersweet chocolate with 1 ½ teaspoons of espresso powder and 60 ml of hot water. Over the simmering water, stir until melted and smooth.
Combine Ingredients: When melted, stir in 170 grams of softened unsalted butter in cubes until fully incorporated, then pour this mixture into your cooled egg yolk base.
Whip Egg Whites: In a clean mixer bowl, beat 4 egg whites with 1 teaspoon of kosher salt on medium speed until soft peaks form. Gradually add 12 grams of granulated sugar, whisking until you achieve stiff peaks.
Incorporate Egg Whites: Mix a quarter of the whipped egg whites into the chocolate mixture to lighten it. Then gently fold in the remaining egg whites, being careful not to deflate them.
Chill the Mousse: Pour the mousse into a serving bowl or individual ramekins. Cover tightly and refrigerate for at least 4 hours, ideally overnight.
Make Chantilly Cream: Just before serving, whip the 238 grams of heavy cream with 1 teaspoon of vanilla paste until stiff peaks form.
Serve: Spoon the mousse into serving dishes and top with the Chantilly cream and a sprinkle of flaky sea salt for that perfect finish.
