How Do You Tell If An Egg Is Bad

So, there I was, standing in my kitchen, staring at an egg like it was a crystal ball about to reveal the secrets of the universe. You know those moments, right? When you're suddenly faced with a task that seems as complex as solving a Rubik's cube blindfolded? Well, for me, that task was figuring out if this egg was still good to eat.

Now, I'm not one to waste food, but I also don't fancy a bout of food poisoning. So, I decided it was high time I learned how to tell if an egg has gone bad. I mean, it's not rocket science, right? But then again, neither is making a peanut butter and jelly sandwich, and I've managed to burn those before. So, let's dive in, shall we?

First Things First: The Float Test

Alright, so you've got your suspect egg. The first thing you want to do is give it the float test. Fill a bowl with cold water and gently place your egg inside. If it sinks to the bottom and lays flat on its side, it's still good to go. But if it stands upright on the bottom, it's still safe to eat, just not as fresh.

Now, here's where it gets a bit tricky. If your egg floats to the top, it's time to say your goodbyes. It's gone bad, my friend. But why does this happen? Well, as an egg ages, the air cell inside it gets bigger. When it's big enough, the egg will float. Gross, right? But don't worry, we'll get through this together.

Next Up: The Sniff Test

Alright, so the float test has given you a hint, but it's not foolproof. Time for the sniff test. Crack that egg into a bowl. If it smells fresh and eggy, you're good to go. But if it smells off, like sulfur or rotten eggs, it's time to chuck it. Trust me, you don't want to risk it.

Here's a pro tip for you: if you're not sure about an egg, crack it into a cup of water first. If it sinks and the yolk looks normal, it's good. But if it floats or the yolk looks weird, it's not. This way, you won't have to deal with a nasty surprise in your omelette.

Last but Not Least: The Candle Test

Now, this one's a bit more dramatic, but it's also a bit more accurate. Hard boil your egg, then carefully crack the shell without removing it. Hold the egg up to a candle or a bright light. If the inside is red or iridescent, it's still good. But if it's green or gray, it's time to say goodbye.

Here's why this works: as an egg ages, the egg white becomes more alkaline. When you heat it, this reacts with the iron in the yolk to create a color change. The green and gray colors indicate that the egg is old and has a higher risk of salmonella.

Bonus Round: The Egg in the Fridge Test

Alright, so you've got a dozen eggs in your fridge, and you're not sure how old they are. Here's a quick trick: check the sell-by date. If it's more than a month past that date, it's time to be cautious. Also, keep an eye out for any cracks or leaks in the carton. If you see any, it's best to err on the side of caution and toss them.
