You won't have to watch the boiling pot with the BeepEgg Boiled Egg Timer. This egg cooker measures the core temperature of your eggs as they boil to ensure they're done how you want. Keep this egg cooking alarm at the same temperature you keep your eggs, and it'll perform accurately. It's best to store it with your eggs in the fridge—if that's where you keep them—so the BeepEgg has the same starting temperature. Then place it in the pot of water with the eggs you're boiling. You can boil as many eggs as you like. The egg timer just needs to float in the pot with them. Additionally, this timer plays a different song for each level of cooking: "Oh Susanna" indicates soft boiled, "Take Me Out to the Ballgame" indicates medium boiled, and "Hail Hail All Gangs Are Here" indicates hard-boiled eggs.
