How do you store them for the long term...???
Freeze them.
Don't know if you're still here, CM, but for the record, when freezing tomato puree or anything liquid, use good freezer bags, and thaw them in a bowl. Once in a while they leak through a seam or a hole in the bag.
Finished breakfast coffee and thinking about what to do today. Need to check cameras.
My day is all laid out for me.
I have days like that too, but not today. Sometimes an afternoon is just made for sitting in the shade with a glass of iced tea looking at the trees.
