Ready for the most low-tech, surprisingly reliable method ever? It’s the spin test. Take your egg out of the boiling water (carefully!), and give it a gentle spin on your kitchen counter. Watch it closely as it twirls.
If the egg spins smoothly and evenly, like a little top, it’s fully cooked inside. But if it wobbles and spins awkwardly, like a drunk little dancer? That’s a liquid center still sloshing around inside. See? Your kitchen is a science lab, and you’re the star scientist.
You can also try the quick stop trick: spin the egg, then tap your finger on it to stop it. If it stops instantly, it’s cooked. If it starts wobbling again after you stop it, the liquid yolk is still swishing around. It’s almost magical, and it makes you look like a wizard at brunch.
