Place all of the ingredients (except the agave) into the blender and blend until smooth.
Taste the mixture to determine the amount of sweetener needed and sweeten to taste.
Pour the mixture into your ice cream maker and churn according to manufacturers directions. Once the ice cream maker has finished its cycle pour the sorbet into a container and freeze. You may want to take it out of the freezer and mix it quickly every 30 minutes for 2 hours to keep the consistency even.
If you do not have an ice cream maker, pour the sorbet mixture from the blender into a freezer safe container (preferrably a shallow container to expedite freezing) and take it out of the freezer to mix it every half hour until the desired consistency is achieved.
Remove from the freezer 20 minutes prior to serving to soften slightly.
