Pumpkin pie vs. sweet potato pie
As the eatin' season begins, it seems to me that someone out there can discuss the difference between pumpkin pie and sweet potato pie. I've only had SP pie once, a good while back. But it seems to me that they're both basically the same thing, a custard with cooked, pureed flesh and similar spicing, which is variations on cinnamon/ginger/nutmeg/mace. But that's only a theoretical description. Lots of folks seem to prefer one to the other. Help me out here. What's the difference? Why do you prefer one to the other?
