Since it will be cold for some time, I was thinking of using my detached, unheated shed to pickle some veggies. But another thought I was having was to actually cure/can some herrings or sardines (or another kind of blue fish) in a jar with water and salt.
Is it possible to do that similar to how veggies are pickled? I was thinking that the brine I would put the fish in would act as a preservative and the fish would be edible after some time of curing? Is this doable or is it just a bats**t crazy idea?
