Personally, I think anything ‘pumpkin’ should be banned as a crime against humanity. The only useful purpose for a pumpkin pie is to throw at someone.
What most of us think of as “pumpkin” is actually the traditional pie spices, and it’s really easy (and cheap) to overdo the spices or get them out of balance. I have made “pumpkin” pie out of carrots and people could not tell the difference.
