Set the stage: Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper.
Make the filling: In a bowl, mix together the mascarpone, honey, pistachios, and cardamom until smooth.
Assemble the spiral: Lay one sheet of phyllo on a work surface and brush with melted butter. Top with a second sheet and brush again. Spoon a thin line of filling along one long edge, then roll the phyllo into a loose rope.
Shape: Coil the rope into a spiral on the baking sheet. Continue adding rolled sections, wrapping each new rope around the spiral until all phyllo is used.
Bake: Brush the top with the remaining butter and bake for 25 minutes, or until golden and crisp.
Finish: Dust with powdered sugar and top with POM Wonderful Pomegranate Arils and extra chopped Wonderful Pistachios. Serve warm or at room temperature.
