Sweet Potato and Pear soup

I was all prepared to do a light  mediterranean  dish but the weather  yesterday changed my mind ,it was windy and wet ,wet ,wet .So I decided I should cross my original mediterranean idea with something hearty.
So I cam across this soup and just had the right ingredient in the  cupboard
If you're in the midst of winter gloom or happy when you feel the early days of spring  upon you, this is the one for you . It's by no way a run of the mill soup  its fruity and could  easily be served in the summer as a chilled soup,it’s a full-bodied soup not for you if your like more of a broth .
When you first taste it the pear gives u a fruity taste on your palate the sweet potato is more subtle it has a crunch texture from both the pear and sweet potatoes  if you want to cheer up  or do something special and unusual this is a simple way of doing it .
