Curried ' Pumpkin ' Bisque

Why I Love This Recipe
This is just as good with Butternut Squash and yes, you can use an actual Sugar Pumpkin as well but I find it to be too sweet for my taste.
Choose your curry, be it Thai Red or Green; Indian Curry or Moroccan Ras Al Hanout. Personally, I like Indian Curry powder (Yellow) for this... But Ras al Hanout is good too.
