Cut off the end of the pears and peel them. Slice them length-ways into quaters.
Juice the oranges and add the juice and water into a saucepan, stirring well.
Once the liquid begins to bubble, add the pear quarters and place the lid on the pan.
Simmer for 10-15 minutes on a low heat until the pears are soft.
Once pears are soft, blend until smooth.
