Place all ingredients in a blender, and blend until smooth.
Place the resulting puree in an ice cream machine and churn until frozen. If you don't have an ice cream machine, place it in a freezer-safe container and into the freezer until almost frozen. Take it out, whisk in until smooth, and freeze until solid.
To serve, let it stand at room temperature for about 2-3 minutes until slightly softened, scoop, and serve.
