I'm tellin' ya, if you haven't had a good buttercup squash pie, you haven't lived. . .
Buttercup squash is a smallish, green squash with bright orange flesh. Very tasty when baked with a little butter/brown sugar on top, though you don't really need either. What can I say, I was raised on it.
Just subsitute it for pumpkin in a pie. It will taste better. Probably pumpkin pie would taste better too if you didn't use canned pumpkin, though.
Pecan pie is really, really, really, good. Pumpkin/squash pie with pecans on top is even better.
