OK, here we go, the Great Salted Bean Experiment!
As mentioned, the visual was very appealing, very similar to how they looked when I put them in the crock in mid-September. A few on top were a little (very little) shrivelled, as their moisture had been withdrawn by the salt, and they weren't able to re-absorb it because of their position in the crock.
I soaked some of the beans for about 3 hours in cold water, but was kept from getting back to them during that time, so I didn't change the water as perhaps I should have - though it might not have made much difference.
I covered them in fresh water, and brought them to a boil, and cooked them until done but still crunchy.
Right out of the cooking water they were
extremely salty.
I'm on my own tonight so was able to experiment

. I made a quick chicken noodle soup, with some stock that I made the other day from a stewing hen. I added about half the cooked beans, and let them cook in the broth for a few minutes. End result: the soup was nicely seasoned (only added salt was from the beans), and, as long as I made sure to get no more than one bean piece at a time on my soupspoon, was quite edible. The beans were still very salty, but the soup was not oversalted. (And, as I have mentioned before, I am extremely sensitive to salt, hardly ever use it in my cooking or on my food)
With the rest of the cooked beans I heated some olive oil in a pan, sauteed the beans a bit, adding large pinches of red pepper flakes and the herb savory (Bohnenkraut in German; literally "the bean herb"). The result smelled divine, but I couldn't eat more than a few bites.
So I would say that this was a pretty good way to preserve beans
if one likes salt, and if one can use the beans in a way as to take advantage of their saltiness.
Final grades 1-5:
Visual appeal - 5
Texture - 5 (still crunchy, like fresh)
Use as stand alone vegetable - 0
Use in a mixed dish - 3 (depending on the dish, of course)
Comparison to other forms of preservation - canned - Salted beans were much nicer, very like fresh in looks and texture
Frozen - Frozen win this one, just because they are not salty, but some of the forgotten beans lost in the bottom of the freezer would certainly lose next to the salted ones.
Would I do this again? Yes, I think I very well might. But I would use them as a seasoning agent, not as a vegetable in its own right.
