Can I seal things in the freezer and then use out of the jar and refreeze? I am thinking blueberries and strawberries that I will flash freeze first.

If you flash freeze berries on a cookie sheet and then put the frozen berries in a jar and vacumme seal them putting them back into the freezer after each use I would not be afraid in the least of any contamination, but be wary of freezer burn in the jars, if you understand what I just said in a round about way. I would, however, be cautious about freezing a glass jar. I would feel much better using the vacuum sealing bags from Food Saver, depending what you have in the jars if you flash freeze berries and not liquid that may expand and possibly break the jar, the flash frozen berries may be alright.

Hello JeanneB, I have not tried what you are asking about, but from what I have read so far, as long as the food in the container does not thaw when you remove it from the Freezer, it should be OK to re-seal and re-freeze for later use. I believe that since you have opened the food to new air and contaminates, the shelf life will have been compromised, but if you use the food up within a reasonably short amount of time, you should be fine. The FoodSaver sealer is very handy for re-sealing those foods that you didn't use all of.

I freeze jars all the time. As long as you leave head room for expansion there shouldn't be a problem. Also, no huge temp changes! I wouldn't put hot leftovers in a jar, seal it, and freeze it. Nor take a frozen something out to the microwave or oven. As long as you have decent quality canning jars, they survive well!

yes you can if it doesn't have sugar already in it. I made my first batch last night using frozen strawberries and it turned out GREAT. make sure they're completely thawed out before using.

You can, but I would seal what's inside in a zip lock freezer bag. Make sure the box is upright otherwise it would collapse under pressure. I wouldn't burry it to deep.

I recommend you put the gasket on to the container prior to freezing. I found it can be hard to work with the frozen canister, but when it is room-temperature it is not an issue.

These jars should be fine to freeze in, though I have not attempted to freeze anything in them yet. Make sure you research/Google how to properly freeze goods in a glass jar as any glass jar can be broken through the freeze/thaw process. Sorry I could not give you direct experience with freezing goods in these jars, but hopefully someone will be able to. http://lifeyourway.net/how-to-freeze-food-in-glass-jars/

Do you mean after they've been opened? Because otherwise there'd be no reason to freeze them since they're in cans which should last years and years if unopened. So, if I did get that right, I see no reason why you can't freeze some of this maybe even in a small Tupperware or plastic bag with the air sucked out of it. If you haven't had it already, it's really really good stuff. Enjoy!

No, these containers are not for freezing. You would use the foodsaver bags for that.

You can freeze liquids, but don't fill too high because liquid expand when frozen! Fill to about the bottom or just little lower than the jar lid edge. You can feeze liquids in mason jars as well and there's a "freeze line" just below the lid.

Yes but they don't seal very well so if you are going to freeze for more than a couple of days, freezer burn will most likely occur.

I made blended raspberries and vanilla yogurt together and was pleasantly surprised how tasty they were. When you thaw them out just run them under warm water for 2 to 3 seconds and they come out nicely. I have not froze yogurt by itself but I am sure it would be fine. The portions are nice also!

It is my understanding these containers are intended for dry storage - beans, flour,pasta, sugar, etc. I don't recall reading anything about freezer use.

A great idea is to first freeze liquids in a ziplock bag. Once frozen, open the ziplock, but do not remove the frozen content. Place the unzipped ziplock inside the food sealer bag with the zip facing DOWN. Seal!!

If you put them in plastic bag! In order to really seal a Mason jar, you'd have to have a specially designed top for the jar. Most things that you'd can need heat anyway, I believe you'd just be adding complexity for no benefit. The FoodSaver works great as designed....to seal food in plastic. Canning works great as designed....to seal heated/cooked food in glass/metal. The two processes are different enough that you do not want to mix them.

I'm sorry I don't know the answer to that question. I've never made freezer jam.

Yes, I froze it all the time, in small servings. It does mess with the consistency a bit; I was blending it in smoothies and it wasn't a problem.

I know it is refrigerator safe but I have not placed mine in the freezer. I would assume that if you left the pop-top lid open, that it would freeze properly but I just haven't had a need for that type of situation. Sorry.

I have not used this way, but I imagine they could as long as you don't seal them tight until after the freezing process is done. Product inside jar will expand while freezing and could crack the glass if no room for the expansion. I would put plastic wrap over jar until frozen then add the lid.
