So, I'm living in France and the stores aren't keeping their eggs in the refrigerated sections in the stores. That trips me out! The same with milk... although, you gotta refrigerate the milk once you open it. My question is: how long can eggs be stored at room temperature? The same with mayo. I was always told it has to be stored in the fridge, but is that true? The eggs in commercial mayo are pasturized, and everything else-- oil, lemon, etc. -- those are all fine at room temp. Anyone know? I'm baffled by the mayo. Mayo in the jar at your house-- put it in the fridge. In packets at the burger stand-- room temp (or warmer!) is fine.
