Put about half of the ingredients in the blender. Process until just combined. Pour into freezer container or containers.
Process the remaining ingredients and pour into containers.
Freeze until the desired consistency, shaking or stirring every 45 minutes or so. If you are using individual sized jars, this should just take a few hours. For larger quart jars, closer to 4 hours. If you put it all in a gallon container, it will take closer to 8 hours.
