In a blender or food processor, combine the cottage cheese, fresh raspberries, honey (or maple syrup), vanilla extract, lemon juice, and salt. Blend until smooth and creamy.
In a separate bowl, whip the heavy cream until soft peaks form.
Gently fold the whipped cream into the raspberry mixture until fully combined, being careful not to deflate the cream.
Spoon the mousse into serving dishes and refrigerate for at least 1 hour to chill and set.
Before serving, top with additional fresh raspberries for garnish.
