I need help! I just finished making sauerkraut and was using a mason jar inside of a larger mason jar to weigh down the cabbage. Now, I can't get the inner mason jar out.

I've tried soap around the rim of the jars.

Any suggestions?

    Try putting ice in the inner jar and put the outer jar in hot water. – Ross Ridge Mar 4 '15 at 6:21

    I should have specified that the inner jar is full of water and we can't take off the lid. We tried placing ice on top of the inner jar to no avail. – jmdg125 Mar 4 '15 at 6:23

    Can you puncture the lid of the inner jar? Those insets are disposable, right? – Catija Mar 4 '15 at 6:53
  • Go Red Sox! That is all. – ElendilTheTall Mar 4 '15 at 9:57

    How did you get the sauerkraut out?! – SourDoh Mar 4 '15 at 15:48

Ok, first you had me wondering "How did he get the small jar inside?", but having kids I quickly realized this is a futile question. (For those w/o children, read Douglas Adams...)

The standard procedure for detaching two jars / glasses that are stuck, would be putting ice cubes in the inner one and then placing the outer one in hot water. But you said you can't open the inner one which is full of water?

Well, ice is frozen water. So freeze the entire contraption until you have one large ice cube in the inner jar. Proceed as usual.

Your inner jar might break due to expanding ice or the outer due to thermal shock, but currently you have two unusuable jars, after this, you might have at least one good one...

    Chilling might be enough to avoid the possibility of the middle jar bursting from freezing (as someone who had a water line freeze not 2 weeks ago) ... and then put the whole thing in hot (but not boiling) water. – Joe Mar 4 '15 at 21:23

Whelp - I know you all have been patiently awaiting the outcome of this puzzler.

I ended up freezing the entire thing as suggested by @Stephie. This didn't quite work - the inner jar still wouldn't come out.

So then I tried sticking the cold contraption inside of some warm water (off the boil for 10 minutes), which split the large outer jar in half.

So, I still have the small jar in perfect shape - but the large jar ended up dying a slow death. Don't know if this really constitutes an answer, but it should at least serve as a lesson for the next sauerkrauter using a similar mason jar method...choose your jar size wisely! Thanks everyone.

  • I'd suggest getting some Pickle Pebbles or something similar, they are much better for weighing down sauerkraut and don't get stuck. I learned as much after I also broke a big jar trying to separate it from a smaller jar that had gotten stuck in the mouth. At least Mason jars are cheap. – Dan C Sep 17 '15 at 17:01

Mine got stuck like that too. All i did was pour a mixture of oil and soap around the small jar (inside the big jar) and it slid out. :)

Ball jars are not exactly round. Try rotating/turning the inner jar so it's positioned differently in relation to the outer jar.

Yes, you could puncture the lid. You should never re-use the lid. Keep the ring. Throw the liner (lid) away after one use.

If you happen to have what's called a spring hook, you could hook that under the outer edge off the liner and pull off the lid.

You could also take a hammer and pound a screw so it pierces the lid. Then screw it in a bit further so it grabs the lid. That will help get a good grip on the lid and pull it out by yanking on the screw. The bigger the screw, the better to grab hold of.

  • Never mind. Now I see you solved it...sort of. – user36802 Sep 17 '15 at 14:46
