I am new to this forum, and I was wondering if anyone else has encountered my problem. Often when I make jelly, it reaches set point nicely, but when I put it through the water bath process to seal the jars, it seems to "un-set". I usually have a bit left over that I put in a container and put straight into the refrigerator, and this sets nicely, but the jelly in the jars that has been through the heat seal process goes back to being liquid. What am I doing wrong???
I think your problem is the water bath process itself! Cook your jelly, place it in clean, sterile jars. Apply the lids and rings and leave it alone. As it cools you will "hear" it seal. The lid will "ping"! Read the instructions that come with your Shur-Jel (pectin) product for other tips! Also, you can read this link site for great information.
Thanks Uncle Bob - you are probably right about the water bath process, but because I sell my jellies at local farmers' markets, and we have very strict food safety laws in my part of Australia, I have to heat seal the jars. The puzzling thing is this doesn't always happen, and it doesn't seem to have any pattern with regards to type of fruit, quantity made etc. It is very frustrating!
google "runny jelly" there are ways to fix it. I just read one that said the reason its runny is that the boiling time (cooking the jelly) wasn't accurate.
I would read from more than one source on how to fix it. good luck!
