This heat sensitive Egg Timer from Burton Cooking Tools changes colour to show when eggs are soft, medium, or hard boiled so you will have perfectly cooked eggs every time.
Simply place the Egg Per’fect Egg Timer in the pot along with your eggs and as the water boils the Egg Timer will gradually change colour to show you when your eggs are cooked just the way you like.

For best results: Use room temperature water and bring eggs and Egg Timer to a medium boil. After use, allow the Egg Timer to cool slowly; do not immerse in cold water.
