sounds great!
but I hafta say, this time of year, why not use fresh pumpkin from the farmer's market or store? Pie pumpkins are best, but a small jack-o-lantern pumpkin still has plenty of "meat" and flavor. All you have to do is cut it in half, scoop out the seeds and stringy parts, put it cut side down on a baking pan (or a sheet with a lip) and bake at about 350F until the shell side is soft to the touch. Then let it cool and scrape out the pumpkin. You can puree it if you like, but I prefer a little texture to my pumpkin pies. Yummy!
