This is the secret to perfectly boiled eggs. Simply pop it in the pan with your eggs and as your eggs boil, the egg-shaped timer reacts to the heat, changing color to show how well done the eggs are. The indicators show when eggs are soft, medium and hard boiled. When the egg is just the way you like it, remove it.
The heat-sensitive design of the timer means eggs are always done well, no matter the temperature of water or number of eggs. The timer measures 5cm by 4cm, is made of food-safe polyresin and costs Sh925.
