How to Tell If an Egg Has Gone Bad

Six days. That's how long it takes for egg doubt to take hold. By egg doubt, we mean the burning and impossible-to-answer question: Are these eggs bad? Are these eggs good? Will I die if I eat them? It happens to all of us, whether we're staring at the last two eggs left in the dozen or rediscovering an entire carton that was hidden behind a not-so-careful placement of the milk.

But those questions are now answerable. We have a trustworthy (and pretty straightforward) way to judge if your eggs are still cool to use. All you need is a bucket, glass, pot, or swimming pool full of water.

Here's your gauge. Drop an egg into water. If it sinks to the bottom, it's fresh, perfect for poaching and soft-boiling and making souffles. If it stays submerged with its wide end up, it's older but still good for most uses, especially hard-boiling (where the egg is cooked all the way through). If it floats, toss it. That's a bad egg.
