I’ve never tried to can crackers for long term storage but if you don’t have kids who consume all snack foods as soon as you buy them, then this may be a good idea. I think I’ll give it a shot soon just for grins.
I did notice that at the end she used the vacuum foodsaver to remove excess oxygen from the jars after she cooked them in the over; I’m wondering if it wouldn’t have been better to remove the oxygen first and then cook them in the oven? I really don’t know the answer to that one.
You can skip roughly the first half of the video as that’s mostly just her adding crackers to the jars…
