I have read on multiple canning sites that you can freeze jam in glass jars. Has anyone actually done this successfully? Under what circumstances would it be preferable to putting the jam in plastic containers?
It just doesn't seem very safe to me (I fear the glass would break).
Previously, I have bought plastic containers to freeze jam in, but they did not seal very well. I'm wondering if glass could perform better? Or, should I just find better plastic containers?
