How Long Homemade Tomato Puree Lasts in a Mason Jar

Question

I grew, harvested and put through a food mill part of my crop of tomatoes, enough to fill a quart-sized Mason jar.  Life events kept me from using this beauty for a while and now I'm wondering -- how long should this last?  I'm almost afraid to open the jar!  But I would surely like to use them.

Hi Jim - Were they formally canned in sterilized jars? If they haven't been officially canned they will generally only last as long as any fresh tomatoes would last - about a week to 10 days in the refrigerator. If they have been properly sealed, they can be stored in a cool, dry place for about a year. Hope that helps! Best, Lynn C.
