Oooh, hadn't thought of drying green beans! I think salting them is the preservation method I've heard of. (Or canning them, but that needs a pressure canner, and no, an Insant Pot won't do: it's too small and so cools down too quickly to be safe with recipes designed for 17qt or larger pressure canners.)
Off the top of my head:
1:20 ratio of salt to veg (so take weight of veg and use 5% of that as
salt) or a little less will give you lactic acid fermentation, i.e.
sauerkraut and its ilk. You need to make sure the veg stay under the brine
(which is produced naturally, do not add water) or the top bit goes off and
can ruin the whole batch, there are special weights etc you can buy but
rocks will do, don't use anything metallic though. Keeps for weeks or
months, allegedly good for gut health.
5% to 20% salt: not a great idea, slows down lactic acid fermentation, but
still allows other nasties to grow.
25% salt and above: basically replaces the liquid in the veg with brine,
keeps for months or years, you will almost certainly need to soak the veg
in a few changes of fresh water to make them edible but then they are
allegedly superior to frozen or canned. The classic to store this way is
green beans. Preserved lemons also use something like this method. I stored
several kilos of chestnuts this way in 2004, it worked.
In all of these, slice the veg fairly finely first (half a cm thick should
be OK, so not-gigantic green beans are fine as-is). Storing somewhere cool
is best, but if you have the right salt ratio, actual refrigeration
shouldn't be necessary.
Best to use pure sea salt or rock salt or similar, not iodised salt, and
not table salt with anti-caking agents. (But if you do absolutely have to
use those for dry salting because you can't get other ingredients, just...
use a bunch more salt, like 30% or 33%, and it should be okay.)
Advantages:
- still works if you live in a damp English house in a damp English town
- in salt-curing (>25% salt) you can pretty much tell if something has gone
wrong, because it'll smell... funky
- doesn't require you to decorate all your radiators with strings of veg
for weeks on end
- way less time consuming than canning or hot-pickling (which is a whole
other thing)
- doesn't require fuel at all
- salt is still pretty cheap
- cheap plastic containers are just fine
- works for low-acid veg that can't be canned in a boiling water bath
- if you salt mixed veg you can basically rinse the worst of the salt off,
add water, and now you have soup
Disadvantages:
- if you are planning to do this on any large scale, you will need a metric
fucktonne of salt, and it feels a bit silly to have that much salt in stock
and then not use it
- not good to feed these foods to people with sodium-sensitive hypertension
(which isn't most people, to be fair, but still)
- not great for very wet vegetables like tomatoes
- I'm just someone on the internet so you probably shouldn't trust me, but
it's very hard to find instructions on this online that aren't all about
sterilising the jars or refrigerating your lactic acid ferment or whatever.
I think I first read about this in "The Self-sufficient Gardener" by John
Seymour (I think), prod me next week -ish and I can check.
I am currently wondering whether buying a fridge-freezer to replace my existing too-small fridge and in addition to my existing small freezer is more important than paying off my credit card. But I worry about power cuts.
Local veg bloke went weekly rather than fortnightly because this is the time of year he has food, and I am not getting through it but need to find a way of preserving stuff before we are back to fortnightly cabbage and swede.
