I've had so much fun making these and canning them in the past weeks.
I did have a little issue with the applesauce "siphoning" when I tried to can it -- somehow the seal failed and it oozed down the sides of the ostensibly sealed and processed jars. I took a little sauce out, used new lids, and reprocessed with no ill effects. Phew.
The apple butter is really wonderful -- made with cider, a little cinnamon, and some sugar -- spread on pumpkin bread, it is amazing.
I'm looking forward to giving it to friends for the holidays.
