Wearing your rubber gloves, wash and skin pears. Be careful of the very tiny spines. Add all ingredients except mint to a blender and puree until smooth. Reduce liquid in half on medium heat. Strain and let cool.
Note: Before freezing the puree, adjust the flavor with sugar and cranberry juice, to taste. Freeze puree in an ice cream maker and you're ready to scoop.
Garnish with fresh mint.
