Canning jars in the freezer?
#1
Has anyone ever used canning jars in the freezer? We're starting to buy thinks like ketchup in large quantities to save money, but we need to find a way to preserve the excess until it's needed. We have a vacuum sealer, but the bags have limited reusability, and we don't have a large supply of freezer boxes at this point.

My wife has recently given up her full-time job to stay at home, so we're watching costs very closely and trying to make use of everything we already have on hand. That led me to ponder vacuum sealing some of this stuff in canning jars and then just putting them in the freezer rather than actually going through the canning process to preserve them.

I have, pints, quarts and 2 quart jars. I use the foodsaver to remove the air and vacuum seal a lid on it, then put a ring on them and stick them in the freezer. I just stuck some pineapple in not too long ago.

Once upon a time I threw some in the freezer 2/3 filled with water to have a little extra "cold" for an impending power outage.

Yes, it did crack them, so I'd be careful with anything liquidy.

I'm assuming you didn't vacuum seal these jars?

Not sure if that would even make a difference, though.

If you're freezing things that don't expand much when frozen, then I'd say glass jars are going to be safe. Just be aware they'll break easier if you drop them.

As for freezing water in case of power failure, we used plastic apple juice jugs that were cleaned out. We had four frozen and ready to go in case of extended power failure from the storm last year.

I've frozen stuff that has been vacuum sealed in the past. No problems.

If you don't have a vacuum sealer, leave the lids off overnight for freezing and put them on after the liquid has expanded. Storage time will be shorter than if you vacuum sealed (removed air which contributes to freezer burn)

I would think it would be safer and more space-saving to store your freezer foods in freezer bags. With ketchup, then you can just cut a hole in the bottom and squeeze it into your bottle.

I wouldn't think I would want to freeze anything glass, but evidently people here do it. I would think that freezing things flat in freezer bags would be the best choice though if possible. That way too you can more safely microwave it if you need a quick thaw, etc.

Our tomatoes didn't do well this year, but last year they did, and I made a lot of homemade tomato sauce and just froze it in freezer bags rather than canned.
