Ingredients
Scale
- 2 1⁄3 teaspoons (7 grams) powdered gelatin, 1 packet Knox
- 3 tablespoons cold water
- 10 oz (2 1/2 cups) fresh or frozen raspberries, thawed
- 1⁄2 cup granulated sugar
- 2 tablespoons fresh lemon juice
- 2 cups heavy whipping cream
- 1⁄4 cup powdered sugar
- 8-12 fresh raspberries and extra whipped cream, for garnish (optional)
Instructions
- prepare the gelatin
Begin by sprinkling the powdered gelatin over 3 tablespoons of cold water in a small bowl. Allow it to bloom for 5-10 minutes. This step is crucial for achieving the mousse’s characteristic structure and smooth texture. - create the raspberry syrup
In a medium saucepan, combine the raspberries, granulated sugar, and fresh lemon juice over low heat. Stir frequently as the sugar dissolves, releasing the natural sweetness of the berries. Once the mixture becomes syrupy, carefully strain it through a fine mesh sieve into a heat-proof bowl to remove the seeds, ensuring a smooth consistency. - combine the syrup with gelatin
Transfer the strained syrup back to the saucepan. Add the bloomed gelatin and gently heat it over low flame until the gelatin dissolves completely. Pour this mixture into a large, clean bowl and set it aside to cool. - whip the cream
Using a hand mixer or stand mixer, beat the heavy whipping cream on low speed with powdered sugar until soft peaks form. Gradually increase the speed to medium until stiff peaks develop. The whipped cream should be fluffy and hold its shape without being over-whipped. - fold the mousse
To lighten the raspberry mixture, incorporate 1/4 of the whipped cream into the cooled syrup and stir until well blended. Then, delicately fold in the remaining whipped cream using a spatula, ensuring no white streaks remain for a beautifully homogenous mousse. - chill and set
Divide the mousse evenly among 4-6 individual serving dishes, depending on your portion preference. Cover the dishes with plastic wrap and refrigerate for a minimum of 2 hours. The chilling time allows the mousse to firm up into its iconic light and airy texture. - serve and garnish
Right before serving, add a dollop of whipped cream and top with a few fresh raspberries for a delightful garnish. These additions not only enhance the presentation but also add a burst of flavor and texture to every bite.
Notes
- substitutions
If fresh raspberries are unavailable, high-quality frozen raspberries work just as well. Simply thaw them before use. For a different fruit profile, try using strawberries, blackberries, or blueberries, adjusting the sugar to taste. - garnish options
Swap fresh raspberries for chocolate shavings, crushed cookies, or a drizzle of raspberry coulis for a more indulgent presentation. - serving ideas
Pair this mousse with a crisp glass of sparkling wine or a dollop of crème fraîche for a luxurious touch. Alternatively, serve alongside buttery shortbread cookies for a delightful contrast in textures. - make-ahead convenience
Raspberry mousse can be prepared up to a day in advance, making it an excellent choice for entertaining. Simply store it in the refrigerator and garnish just before serving.
