“A prepper on that Prepper TV show from years ago suggested coating eggs in caster oil allowing them to last for months.”
Yep. In America, eggs are washed in warm soapy water before getting weighed and cartoned. That removes their natural air-blocking coating.
Carton eggs are not washed in most other countries (their women can deal with eggs the way they exit the hens).
Those foreign women are wonderfully resourceful aren't they?
Wonder what they do with the bacteria on the eggs?
