A great way to improve your pumpkin soup is to add a little diced bacon. It still blends smooth but is tastier.
If you don't allow the soup to cool a little before blending, the heat may cause the soup to blow off the blender lid, leaving you in a big mess - I learnt this the hard way!
Really yummy...see my tweak, cos I changed it a bit, mainly by leaving out the garlic which seems to ruin pumpkin soup for my kids - 06 Jul 2010
Used different ingredients. I used a little butter (about 25g) for flavour and less oil, left out the garlic and replaced the cream with a small can of light evaporated milk. I liked the idea of roasting the pumpkin, instead of my usual simmering on the stove. Made lovely soup. - 06 Jul 2010
