Hiya, I'm wondering if anyone is familiar with preserving/canning using bottles (not jars) - specifically the swing top variety (maybe called Grolsch?) that have a ceramic plug with a rubber gasket and a wire bail. I have several of these that I would like to use for preserving homemade ketchup and other sauces, however once these are sterilized and filled, I'm not sure how to process the bottles. Can they be processed in boiling water like regular canning jars? It seems if the wire was snapped in place, there would not be enough give for extra air to bubble out during the boiling process - I'm afraid the bottle could burst in this case. However if you just put the stopper on top of the bottle, without using the wire to lock it down, it seems like there's not enough resistance and water would just seep into the bottle.
Has anyone worked with these bottles before? All the info I've been able to find so far pertains to beer bottles which don't seem to undergo this hot processing.
Thanks in advance,
