Pour the mascarpone and honey into a large bowl and beat quickly. Open the cardamom pods, carefully remove all the seeds and grind them in the small bowl of a food processor. Pour the very cold cream into a bowl, add a pinch of ground cardamom and whip with a blender until you have a nice Chantilly cream. Fold this into the mascarpone. Spoon the mousse into 2 small bowls and serve very cold. Add a sprinkling of fresh or dehumidified pollen to decorate and flavor the mousse.
