Quarter the pumpkin. I had Matthew do this because it was difficult. Sarah suggested sprinkling Pumpkin Pie Spice over the top, she said it mostly made the house smell nice. I did that, but I can't smell, so I can't tell you if it worked.
We put it on a baking sheet covered with foil and roasted it at 35o. I don't know how long. We were watching "The Office" on DVD and cutting out another project, and I kind of forgot about it until Matthew reminded me.
Then I carefully scraped all of the inside away from the outside, which was papery thin, and blended it one quarter at a time in the blender. I did this while it was still very hot. It would probably be a good idea to wait. Each quarter was about 2 cups of pumpkin.
It was fun, but seemed like an awful lot of work. Also I'm not sure what to do with the pumpkin now. I can make a pie...but... come to think of it, I'll need a recipe for that. We always used the recipe on the back of the can of pumpkin to make the pie. I guess I used the wrong kind of bags, there's no recipe on there.
