Open eggs carefully...
I used to buy refrigerated store eggs and keep them without cooling in the southeast USA in the summer. They were probably never kept more than a couple/few weeks and I only had one egg ever go bad, but 'boy was it bad'. Put me off eggs for long time.
IF you keep eggs w/o a fridge it would be good to get in the habit of float testing or sniffing or maybe pricking with a needle and sniffing before breaking because "YOU WILL KNOW RIGHT AWAY" and if you break a rotten egg into a bowl in the galley it will ruin your day. When we go back to living aboard I plan to get into that habit so as not to relive "that terrible day".
