Boiling eggs should be simple, but how do you know when they’re ready? Whether you’re hard boiling eggs or you prefer a runny yolk to dip your soldiers into (sometimes kids food is so comforting!), it’s difficult to know how long to boil eggs for. Egg timers make the process easier and I’ve come across the king of egg timers! Egg-Per’Fect is a colour changing egg timer that senses heat, not time consistency to help cook perfect eggs regardless of egg quantity or altitude.It sits in the pan with your eggs while they boil and tells you when they’re cooked to your taste. Graduated scales show when eggs are soft, medium or hard by sensing heat instead of time. This egg timer has a sensor which accounts for the number of eggs, the amount of water and even the altitude at which your eggs are being cooked. Soft boiled eggs are exactly as you like them and hard boiled eggs are never left to boil too long.
