The chocolate mousse—one of Chef Dominique’s favorite desserts on its own—is best made and used straight away while it is fresh and at the peak of its flavor and texture. This chocolate mousse forms an integral part of Chef Dominique Ansel’s chocolate cake recipe. Traditional chocolate mousse ingredients are heavy cream, egg yolks (or egg whites), sugar, vanilla, and dark or semisweet chocolate chips. Traditional chocolate mousse gets its creamy texture from creating a custard with the eggs, sugar, and cream. Traditional chocolate mousse doesn’t include gelatin because it’s meant to be soft and eaten soon after being made. Chef Dominique Ansel’s chocolate mousse recipe omits the eggs, sugar, and vanilla, doubling down on dairy with cream and milk. Chef Dominique incorporates gelatin into the mousse for his chocolate cake to stabilize it and give it a pleasing texture, even when chilled. Gelatin comes in two forms: sheets and powdered. Either can be used in place of the other (at a ratio of 3 sheets per 1⁄4-ounce packet of powdered gelatin). Tips for Making Perfect Chocolate Mousse 1. Making mousse begins with making ganache. Pouring the hot milk over the chocolate helps to melt the chocolate fully so it creates a ganache with a smooth texture. 2. Once the ganache is made, it’s important to allow it to cool to room temperature so that when it is folded into the whipping cream, it does not melt the cream, thus deflating it and knocking out all the air that helps give the mousse its light, airy texture. 3. Consistency is key when pouring the mousse onto the cake. Use the bottom of the ladle to lightly tap the mousse, which will help create an even layer across the biscuit and over the top of the finished dessert. 4. The cake will need ample time to freeze so that it sets properly so do not try to rush this step. This step is essential to creating the ideal texture for the mousse, which should always be served chilled. If it comes to room temperature, it can become too soft to stay in place while cutting the cake. Chef Dominique Ansel’s Chocolate Mousse Recipe - 2 each gelatin sheets (silver strength/160 bloom) - 448g (2 cups) heavy cream - 312g (1 1⁄3 cups) whole milk - 308g (11 oz) dark chocolate (70% cocoa content), finely chopped Tip: If you can’t find gelatin sheets, use powdered gelatin. One gelatin sheet = 1 scant tsp (2.3g) powdered gelatin. For every tsp of gelatin, bloom in 1 tbsp (15g) water. Equipment - Stand mixer fitted with whisk attachment - Hand blender - Whisk - Spatula - Thermometer 1. Soak the gelatin sheets in a bowl of ice water until soft, about 20 minutes. (If using powdered gelatin, sprinkle 2 tsp (6g) gelatin over 6 tsp (30g) water in a small bowl, stir, and let sit for 20 minutes to bloom.) Tip: Whether using sheet or powdered gelatin, you must use cold water since warm or hot water will immediately dissolve the gelatin and you will not be able to work with it. 2. In a small pot, brin...
