I've tried several butternut soups and this is the best of the bunch. Every part of the squash gets used, adding lots of flavor. You can store it in the refrigerator (or so I hear) and reheat, but never boil, the soup.
How sweet it is!!! The original recipe in a community cookbook specifies 400F and I haven't had any problems - but I need a new stove; however, I've decreased the temperature to 350F based on the comments & suggestions from Zaar chefs.
