If you’re cruising outside the US, you most likely get non-refrigerated eggs and don’t store them in the refrigerator. (Read more about storing eggs outside the refrigerator.)
Many people who store eggs without refrigeration like to turn them over periodically so that the yolk doesn’t “stick” to one side. Turning them also helps if you store them in a plastic “carton” such as these as it helps keep air circulating and thus you’re less likely to get mold on the eggshells from condensation.
I had always heard that you could only store eggs that had never been refrigerated this way. Recently, however, a couple of cruisers — including Sheryl Shard of Distant Shores TV — have told me they’ve had great luck storing eggs that were refrigerated in the store without refrigeration by flipping them every day or two so that the membrane inside the egg does not dry out and let bacteria in.
But it can be hard to remember if you’ve already flipped them today . . . or if someone else on board may have. Reader Jeanne Walker aboard Eagle in the Sea of Cortez came up with this simple way. Of course, it assumes that you know what day it is 🙂
