WHAT ARE YOU CANNING TODAY?

[frustratedearthmother]

I have dozens of those lids...even when I open like jelly, I use the plastic screw on ones. When I'm milking I use glass jars with those lids. Warm milk goes in freezer for half hr to fast chill. The temp change actually forms a nice "seal" with those lids.

Ditto!

when we were buying a lot of commercial jams in the 18oz jars those jars and lids worked fine for canning and sealing up for several years of reuses - i just made sure they were cleaned well and the lids/seals were uniform (no dents in the lids and no strange stuff going on with the sealing compound).

i did not put things in them that were expensive to make but in the end it didn't matter as i didn't have any seals fail or storage problems.
