I like to put a whole "cooking" pumpkin in the oven at about 300 degrees F and cook it for an hour or two, until it smells good and the shell breaks when I press on it. I take it out and let it cool, then cut it open. I separate the seeds for roasting and scoop out the cooked pumpkin. It is so much easier than trying to skin a raw pumpkin.
Now if I can only think of something to do with that lovely hard shell.
