A long time ago, I read about a way that raw eggs can be kept (for eating) for months or more without refrigeration, maybe discovered in countries that don't have electricity. Seems like it involved some kind of "blanching," and not a coating on the shell. Anyone know what I'm referring to? It could be nice for backpacking trips, at least. One way I have sort of "preserved" hard boiled eggs is to soak peeled ones in the leftover pickling juice from pickle jars for a couple days. Gives them a nice sort of chewy texture, and they are yummy! The brand with the yellowish color is my favorite (Fahrman's??). How about any other pickled egg recipes?
