Have you ever tried to make your own pumpkin puree? I have to admit, it's rather a new idea to me, but it's very easy. I was going to write it all out for you, but found another great blog that did it all for me with pictures! She also uses this method for roasting and pureeing butternut squash as a substitute, as I mentioned in a previous post. If you're interested, here's the link:

Just a note for us novices...the big Jack-O-Lantern pumpkins DO NOT work well here! Look for the small, cute pie pumpkins that are about the size of a cantaloupe.
