I also canned pumpkin when I found pumpkins on sale a few weeks ago. I've canned it before. I always sweeten my pumpkin and then when I use the pumpkin I do not add sugar. It is not recommended by the USDA Extension Service to can pumpkin: http://www.fcs.uga.edu/pubs/current/FDNS-E-P.html but I plan on using these jars of pumpkin before they spoil and adding the sugar will help preserve the pumpkin.
I made pumpkin dip weekend before last and shared it with my camping friends, we dipped vanilla wafers in the dip. It was different and tasted like a pumpkin cheese cake. Very simple to make.
1 can sweetened pumpkin
2 packages cream cheese
1/3 cup sour cream
1 tsp cinnamon
1 tsp nutmeg
Soften cream cheese in microwave and stir in remaining ingredients, refrigerate for about 2 hours and serve with vanilla wafers for dipping.
