Here’s a trick that turns you into a kitchen detective. Fill a bowl with cold water and gently drop an egg in. If it sinks to the bottom and lays flat on its side, it’s super fresh. If it stands upright on the bottom (kind of like a tiny submarine), it’s still fine—just older.
If the egg floats to the top? That’s your cue to say goodbye. Floating means air has built up inside the shell over time, which usually means the egg has gone bad. It’s not scary science—it’s just nature doing its thing.
I once did this with a carton that was three weeks past the sell-by date. Every single egg sank like a rock. I made the fluffiest omelet of my life. Nobody got sick, and the planet didn’t gain more landfill trash. A win-win.
