With the Perfect Egg Timer, you will be able to get the desired yolk consistency every time. The concept is simple.
Just drop this temperature-sensitive timer in a pot of boiling water with real eggs and watch as it changes color, indicating soft, medium and hard-boiled stages. Soft boiled eggs are exactly as you like them every time. Hard boiled eggs are no longer over cooked, so they have perfectly colored yolks and a smooth texture.
