Combine the chocolate, heavy cream, and the vanilla in a heat-proof bowl and set it over a pan of simmering water until the chocolate melts.
About 5 minutes before serving, remove the berries from the freezer and place them on individual serving plates. Ladle the warm chocolate sauce over the berries and serve.
Yield: 8 to 10 servings
Note: You can either buy frozen berries, or freeze your own by placing the berries on a flat tray in layer. When the berries are fully frozen, keep them a plastic bag in the freezer. Larger berries, such as strawberries, do not freeze well.
