I don't tend to can much in my quart jars- they are a bit big for my family's needs.
Being constantly short on plastic containers, I realized tonight that I could freeze my triple batch of red sauce in jars. Just be sure to leave enough room for expansion. You can easily thaw overnight in the fridge or sans lid in the microwave.
For whatever reason, I've had no trouble with tomatoes in quart jars, but I broke one once freezing stock in it. The stock didn't reach the lid, but it pushed against the shoulders of the jar and shattered it. (It was a narrow-mouth quart, though, so there was more of a ridge.)
ReplyDeleteWater expands when it freezes. Everything else contracts. Perhaps the increased solids in the tomato sauce reduce the potential for expansion?
