Since it's potato season again and we have lots of tiny little potatoes that will end up in the compost I was thinking about canning them, but I cannot find anywhere that sells any of the stuff other than seriously expensive ball jars and lids (equivalent to $8 each) that would mean I could buy 10kg of potatoes for every jar I made, not counting any cost of the canner itself.
So is there anyone in Europe who knows of a source for such things?
Potatoes are a *very* low acid food, so they have to be canned with extreme caution (or maybe add acid? - point is, do research - I like my permies alive!)
Is there anyway you could dry them instead?
Last fall, I used a dead freezer and layered potatoes in buckets with wood shavings (not as fine as sawdust, but I've heard sawdust works) and they kept really well for at least 5 months. Would that work in your climate?
Sorry this doesn't answer your question. For something that is high sugar or acid I have used old glass jars with original lids and boiling water bathed them.
I can a lot of stuff most of which is sold so I have tons of normal jars (brand new they have to be) but they are not suitable for pressure canning I don't believe, and no these potatoes would be for a specific dish in the winter, small potatoes will not store so they have to be canned. Hmm thinking about it the jars they come in are pretty much the same as mine, I guess I would have to ask the manufacturer what the tollerances are. but that still would leave me in search of a canner.
Some places have the equivalent of a "tool library" which might have loaner canners? Here, I'd just go to the local hardware store - if they didn't have one in stock, they'd have it in their catalog and bring it in for us. I wouldn't go cheap if you're buying though. There seem to be some specific brands out there that people are really happy with. I've got a large pressure canner, but I bought it over 20 years ago, so I'm not so up on the more modern ones. You're looking for something heavy, so if you go looking on the web, check the shipping weight to get some idea of how solid it is. Of course a Stainless steel one will be heavier than an aluminium one, but the last time I was looking it was for a kitchen one and I want stainless for that. If you are only going to use a large canner for bottles, it's less of an issue, but I want mine for making bone broth.
We live in France and do pressure can little pototoes. As a fact, we can a lot of stuff. Here we can buy “Le Parfait familia Wiss” and we brought our “weck” jars with us for watter-bath and pressure canning.
