Creating a delightful Blueberry Mousse is straightforward when following these simple steps:

1. Prepare Gelatin: In a small bowl, sprinkle the gelatin over cold water. Let it bloom for about 5 minutes.
2. Blend Blueberries: In a blender, combine the fresh blueberries, granulated sugar, lemon juice, and vanilla extract. Blend until smooth.
3. Heat Gelatin: Once bloomed, microwave the gelatin for about 10-15 seconds until dissolved (do not boil).
4. Combine Mixtures: Stir the dissolved gelatin into the smoothie blueberry mixture until fully incorporated.
5. Whip Cream: In a separate bowl, whip the heavy cream until soft peaks form.
6. Fold Together: Carefully fold the whipped cream into the blueberry mixture in three additions to maintain the airiness.
7. Transfer to Molds: Spoon the mousse into serving cups or a decorative bowl, taking care to create an even surface.
8. Chill: Refrigerate for at least two hours or until the mousse is set firmly.
9. Garnish and Serve: Before serving, top with fresh blueberries and mint leaves if desired for added color and flavor.

These steps will guide you in making the most amazing Blueberry Mousse that anyone will adore!
