When we returned from vacation the eggs in the fridge had passed their “sell by” date. I was pretty sure they were still good, but wanted to make sure before I fed them to the kids.
This easy test will determine if your egg is good enough to eat, or it is time to toss.
Submerge your egg in water. If the egg is fresh it will sink to the bottom. If it floats to the top throw it out. If it sits somewhere in the middle eat it today!
The reason a fresh egg sinks is because it has a very small air pocket inside the shell. As time goes on the fluid inside the shell evaporates and more gases fill the shell causing it to float.
