I've been waiting for pumpkins to come on sale (after Halloween) so I could try out this recipe. It looks like it could be delicious:

Also, I found this recipe a while back. It goes against some of the principles that I've learned here on the forums and in other recipes, but it seems like an interesting method to try out, especially if pumpkins are cheap and abundant:

Either way, It would be great it you could give some feedback on any recipes you try out. I'll be starting a batch of something with pumpkins in early November!
