Sounds very interesting I've never heard of making egg pickle, my dad is from Pa. and they make pickled eggs and beets and I love them but these are already hard boiled, so now another way to eat eggs, sound yummy too.Egg salt is egg pickle.. It call egg salt because you need to mix salt in warm water until all the salt dissolve then put an egg in the salt water and see if the egg float that mean it salty enough for make pickle then wait until the water cool down to room temperature and put all the eggs in. Let the eggs sit for 20 - 30 days (depend how much salty you want your eggs to be, you can take one out and hard boil in the water to try after 20 days or you can make omelette. The egg yolk will be very hard, rich and delicious flavor. You can smash the eggs yolk to small piece and put on top of cook rice or.. roasted green beans, asparagus with a little ground black pepper on top.. it's very delicious. Vietnamese use salt egg yolk to make Vietnamese traditional mooncake, it's very different with American Mooncake but it's good. Here a Vietnamese Mooncake recipe that I found from Youtube
