Place all ingredients in a food processor or high-speed blender. Blend until completely smooth. Add the water only if the sorbet is too thick for your food processor or blender.
Transfer to a metal loaf pan or freezer-friendly container. Cover, and freeze for 6 hours until firm.
When ready to serve, thaw at room temperature for about 5 minutes to soften, then scoop and serve!
Notes
You can substitute in honey or agave in place of the maple syrup. If using honey, it may change the flavor slightly.
Frozen raspberries can be quite tart, so make sure to taste test the sorbet before freezing it to ensure it’s sweet enough for you!
The sorbet will last for about 1-2 months in the freezer if kept in an airtight freezer container.
You can thaw it to scoop some out and refreeze the remaining sorbet without issue, as well.
