I do have a pressure canner, I'll look and see if the book that came with it recommends anything for pumpkin. I don't know why I didn't think of that.
It's not as bad as it seems. I was very nervous the first few times but have gotten used to it now. My biggest complaint is that it takes forever, time-wise.
Most of the stuff that I like to make can be waterbath canned. Glad I have the pressure one though, for things like stock.
I like it better than water bath canning. My pressure canner is smaller and the pressure method uses less water, so it comes to a boil faster. I'm going to use it for water bath canning of jams, jellies, and pickles from now on. My water bath canner has been sent to the attic to stay.
I'm going to can pumpkin for pies. I book I read said to process it for 40 minutes under 10 lbs pressure for altitudes below 1000 feet; 15 psi for higher altitudes.
