    I wonder if anyone has done any freezing in canning jars? I would imagine that if you are freezing something wet you would have to adjust down the fill level?

    I have a few things in canning jars in the freezer, but usually the contents are dry things, such as potato buds from the LDS Bishop's Storehouse.

    Freezer jam?

    Maybe it is not a good idea? We're getting ready to cook up our bushel of green chili's into the large batch of green chili. I cooked 21 pounds of pork should roast yesterday in preparation for today's big job.

    We are trying to avoid plastic whenever we can. Daughter freezes up berries, fruits, etc in jars in jars in preparation of making smoothies. There is just the fruit, no added moisture. That happens when she runs it in her Vitamix.

    How to Seal and Freeze Jars
    Anyone who has left a can of soda in the freezer a little too long knows that sealing and freezing a closed container of liquid can be a big no-no. What many don't know is that it's still doable with the right technique.

    If you want to seal and save a smoothie or a jar of chicken broth for a really long time, you might consider using a Ball® and Kerr® Mason jar along with your FoodSaver® Wide-Mouth Jar Sealer and 2-In-1 Vacuum Sealing System. If you want to use this handy technique in the kitchen, just follow these tips.

    Pick a Straight Shoulder Jar
    Ball® makes mason jars specifically for freezing. They're made with a straight shoulder. That means there's no curve around the neck of the jar, which makes it easier for them to stand up to low temperatures and expanding liquids.

    Don't Completely Fill the Jar
    To freeze your soups and stews safely, it's important to leave a little space at the top by the lid. It's recommended that you fill the jar enough so that there's at least one inch of space between the liquid and the top.

    Cool Those Contents
    Don't just move a piping hot chili in a jar into the freezer. Glass can crack if the temperature changes very quickly. That's the same reason you wouldn't put a casserole lid in a sink filled with water right after it's been in the oven.

    Cool the jar and its contents gradually by moving it to the fridge first.

    Freeze First
    After lowering the temperature, move the jar to the freezer, but keep the lid off. Even though your mason jars are freezer-safe, glass can still become very fragile when cold. You'll want to wait until the liquid is frozen solid before taking the jar back out and vacuum sealing. Doing this after will protect the substances from freezer burn. Plus, it's a cinch to do.

    Be Careful When Thawing
    When you're ready to savor that fresh food later on, you'll have to take a little extra care. Remember, glass can crack when the temperature changes dramatically, and this goes both ways. Don't heat up that frozen jar too quickly. Instead, move your smoothies or the like to the freezer the night beforehand so it can safely warm up.

    I have about 3 or 4 of those freezer jars but I've only used them for dry storage.

    Never tried freezing food in jars before

    I use the half gallon ball jars for milk and have frozen many of them. I just leave extra headspace and make sure they are upright until it is solid. I've also used the smaller jars for other things like cream and sauces.

    I may have but for sure my mom has. Mostly I use Zip-Loc freezer bags. I'd avoid anything with squarish sides and keep the liquid well below any shoulder. Slightly narrower at the bottom works best.

    I do freezer jam in jars with the twist on lids like you buy on store shelves without any issues. I leave plenty of head space and have never had a problem. I don't see why you couldn't do it in a regular canning jar as well.

    I mostly use ziploc freezer bags as well, but daughter avoids plastic like the plague. She is a world traveler and tells about seeing so much garbage and waste in places. She also believes is really not good for us health wise. She especially doesn't use plastic water bottles.

    I spent most of my day working on green chili's and green chile. I have more to do. I bought and cleaned a bushel of roasted chili's today and cleaned 90 of them, 20 more to go. One double batch of green chile jarred. I will get those in the freezer tomorrow, and have two more double batches to cook up, mostly ready to go.

    I am thinking we will use those 20 chili's for posole, one of our favorite stews, gluten free for daughter. We may even jar and freeze some of that.

    I have a challenge with my back, so I have to pace myself and sit to work sometimes. I cannot stand in one spot for long periods of time, or I will be crawling.

    I don't freeze canning jars but have had one with water in it freeze and bust, what a mess that was.I was just going to leave it in a few minutes but forgot it.
    I learned with bottled drinks in freezer long time ago. Now that is an explosive mess for sure.

    Yes, you do have to be careful when you put liquids in the freezer. I have heard of people putting soda's in the freezer to cool it off quickly.

    My son freezes stuff in mason jars often. He doesn't do plastic anything.
    Sometimes (ok, always) I overpack my freezers and I don't need a glass jar falling out of there, so I don't.

    We have strawberries by the basket. I will core a couple of baskets tonight for shortcakes and pancakes. We have been eating strawberry shortcake for the last week but we arn't tired of it yet. Maybe I will surprise my wife with waffles tomorrow morning. It has been a while since I fixed waffles and they are always good with strawberries.

    We freeze Chili, Taco soup, meatballs, etc in canning jars, just leave space below the jar shoulder when you fill the jar.
