Peel and core the pear, chop it up and put it in a tall blender jar. Halve the washed grapes and cranberries and add. Peel, core and chop the apple and add to the fruit in the mug. Peel half the banana and add in pieces. Pour in the apple juice and puree everything thoroughly. Possibly stir in sugar, it was sweet enough for me. If the drink is too thick, mix in some more juice.
