Preserving eggs with mineral oil is both an inexpensive and speedy process, but you can only use this old homesteading method when dealing with farm fresh eggs.
Because commercial manufacturers of eggs wash the bloom off of the shell and refrigerate them, rubbing mineral oil onto the shell to protect it from air and bacteria, would be useless, and would result in stinky rotten eggs.
Steps to Preserving Eggs in Mineral Oil
Step 1. It takes roughly 1 tablespoon of mineral oil to thoroughly coat approximately 12 to 18 eggs. I really don’t measure exactly anymore, I simply put ample mineral oil in a coffee cup or bowl to coat multiple eggs completely and replenish as necessary.
Step 2. Gently roll each egg around in the mineral oil of use a spoon to lather it on. It’s sometimes easier and far less messy to hold an egg in one rubber gloved hand when going the spoon lathering route.
Step 3. Place the eggs in an egg carton with the pointy side down. You can go bottoms up, but the mineral oil covered eggs tend to suction into the carton holder far more tightly when initially place in the carton this way.
Step 4. Turn the eggs once a month to help prevent the yolks from settling too firmly and bursting the air sack.
- You can store the eggs either in refrigerator, but you really don’t have too. Simply store the mineral boiled eggs in a cool, dry place until ready to use.
- The eggs should remain safe to eat for at least a few months when coated completely with oil and stored properly.
- Do no try to use any oil to preserve eggs other than mineral oil. I confess that I am not clear about the science behind it, but it is the only oil known to work.
