Canning jams in quart jars

Asked July 12, 2019, 9:18 AM EDT

Do you have any information on the time I will need to can peach, or other, jam in quart jars? The recipe calls for pint jars at 10 minutes processing, but I have teenage grandchildren, three of which are boys, and the pint jars would probably last for only one meal!! Any help in converting the time would be greatly appreciated. Thank you in advance.

Hi, unfortunately jam is best when using pint or half-pint jars as larger containers can result in a weak gel, due to residual heat during cooling. This is why you don't see jam made in larger containers.

This is an excellent resource, and the link takes you to a page with good info., see the last paragraph: https://nchfp.uga.edu/how/can_07/prep_jam_jelly.html

You wouldn't want to go to all of the work of canning to end up with a poorly gelled product if you can help it...

Hope this helps. Good luck.
