I made up the Spiced Blueberry Jammin’, canned it in the way AB shows in the episode, cooled the jars and … didn’t seem to get a vacuum on the lids. Not exactly sure why, though I might have second guessed myself because I came back later and the lids didn’t “pop” anymore. However, I had already opened them out of curiosity so they definitely lost any kind of “preserved” that they had.
The jam itself though was pretty good. I don’t usually use a lot of jams and jellies normally, and I’d probably choose strawberry if I did, so even though this was a good experience to learn the basics of preserving, probably won’t make it again.
File this one under: I get the idea.
