Question:
What Bracha do you make on pureed butternut squash soup?
Answer:
The bracha on any pureed soup if there aren't any pieces will be shehakol, this is because the butternut squash is no longer noticeable, therefore it loses it's hoadomo status. This applies even if there are a few pieces of squash in the soup.
