It's debatable if making your own pumpkin puree is going to be better than canned. While you're most definitely going to have a sense of pride in making your own, you'll want to pay attention to the ingredients that are on the canned version to be sure of a difference. A lot of canned pumpkin has extra sugars or additives - and sometimes it isn't even pumpkin! There are some companies that will use squash in their canned pumpkin, so read the labels.
