I made a batch of Dilly Beans, and needed more liquid, I used 5 cups water, 5 cups Apple Cider Vinegar, AND should have used 1/2 cup salt, but only used 1/4.
Woke up this morning and realized it, should I throw them out? or are they ok?
I'd say they are fine, but you can add more salt. You post that they needed more liquid. So you had some to begin with, I assume at the proper ratios, correct?
So the salt is a bit lacking but the vinegar/acidity is correct. Still not a habitable medium for bacteria. You can always add a bit more salt. If you are salting with in recommended ratios, there is some room for deviation.
if you processed them, they have been in a sealed environment so overnight won't matter.
