Eggs

 did you know that you don't need to refrigerate a freshly laid egg?  You don't need to refrigerate eggs at all unless they have been washed.  This is because a freshly laid egg has what you call a bloom/coating that protects it from bacteria.  I've never been to Europe, but from what I hear it is not uncommon for people to keep eggs out on the counter instead of refrigerating them.  Once the egg is washed, it will then have to be refrigerated because you have washed away that protective coating. 
This is something that my mom and dad augue about ofton,
