Freezer πŸ… sauce preserves

I apologize for offending anyone since i know this topic has been addressed. I looked for thread w/o success. Tonight's date night plans are to preserve home grown tomatoes. A concern was mentioned about glass jars breaking. I would think ball & mason jars should be fine but what about other jars that have been sterilized...would they be safe? Is there a way to tell if the hars are tempered, are there marks. Any input would be appreciated. Ty

    Most jars are not tempered. You may get some use out of recycled jars but be prepared for losses due to breaking. I only used glass jars once in the freezer and won't do that again. Even though they were canning jars, they broke at the slightest bump. You can get good quality BPA-free plastic containers that work just fine for freezing most things. Lately, I have been freezing my tomatoes whole, without any processing. They are mush easier to peel from the frozen state and can be made into sauces later when you have more time.

    Yes, I agree with @torey .

    My experience with jars, if you have jars left over from your grandparents day (or parents if you happen to be in your senior years) they usually work just fine as canning jars even if they aren't considered canning jars. But any glass jar from the last 40+ years, well they were not made for long term storage. They weren't designed for hot water/steam baths etc.. Obviously there is a big difference in quality as the years have went by.

    So jar breakage, length of food storage and even food spoilage was more prevalent in jars which were not considered "canning jars". Sometimes, saved jars even had the problem the canning lids would not seal just right because the jar rim is not just the right size.

    If you have to go buy jars because you don't have enough, try freezing this year (tomatoes just cut out the top core and then freeze them whole on a cookie sheet (core side down). Once frozen, throw them in your freezer bag or vacuum seal bag (works better) and place them in your freezer.

    When you are ready to use them, the night before take as many bags out of the freezer as you want to use and place them in the refrigerator. By tomorrow, they have thawed to a perfect stage where you can open the bag, use your hands and the skins slide right off.

    Then spend the next year keeping your eyes open for people who have canning jars they are trying to get rid of. You can usually easily run into people just in your own community who has boxes of them just sitting in their garage, basement or attic. If you have a local Free community paper, place an ad in it "Wanted: Canning Jars". Or on a church or community bulletin board etc. Just look around and see what you have available right where you live. (An example, here in my town (very small and rural) I had to go to the laundromat for a few weeks this past summer and there is a great big community bulletin board in there. It actually had a ton of useful information on it which I never even knew about my town.)

    I forgot about Catelli sauce jars. Some of those products are in Mason jars which take regular mouth lids and rings. They are a nice size, between pints and quarts. Not all of them are the same so make sure that they have the right mouth for a ring band.

    @tilathehunn I have had great success freezing in glass peanut butter jars. They seem to be very sturdy and I have yet to have one break. I do try to keep them in the wire baskets in the freezer and not just kicking around in the main compartment. I stick to the 16-18 oz jars.

    Squat coconut oil jars have also worked well for me. I don't use the ones that are sized like pint canning jars; they look too flimsy. Vita Coco is one brand that has sturdy jars.

    You also don't always know what you're getting. Some mason style jars have lead in them. I stick with ball jars.
