I recycle my Mutti tomato passata bottles for nic storage. They are strong, have a 400ml capacity and a good sealing top with a wide mouth.
I have jars similar to that. But they are old. Worried about lead in them.
I grow my own tomatoes in the summer and puree them so I can have fresh tomato sauce almost all year round. I hate having to buy it in the store.
But's it's a good idea, though, assuming you wash those lids well, which I'm sure you do.
That's why I've been thinking about using Ball jars with plastic lids since I can get some jars for free. I just have to buy the lids. Not sure what to do about that. Not liking the thought of experimenting with my stash.
