I had purchased this neck pumpkin late last fall for a song, but never got around to cooking it off until now. I figured I had better get to it before it passed its peak!
Then, scoop out the flesh out of the shell and puree in a blender.
(My Vitamix has an extra-large jar which worked great for this. I froze the puree in 2 c. quantities so that it's ready to use any time I need canned pumpkin for a recipe in the future.)
