Pickled Eggs Here is a basic pickled egg recipe, it is not intended that this recipe be used to make pickled eggs that would last in un-refridgerated storage. After pickleing it has been suggested that the eggs sit for one week and be eaten before 4 weeks. I would think that this should be safe enough, treat them as hard boiled eggs and you cant go wrong.If one wanted to have a longer shelf life especially un-refridgerated, I think you might need to look at a pressure cooker method. 1 quart vinegar 1 cup water 1 large onion sliced 1 small jar hot peppers A list of seasonings to try add to taste peppercorns allspice tobassco dill coriander another addition possibility that I enjoy 1 can sliced beets 1.
