Egg Perfect Boil-in Timer

The Egg Perfect timer sits inside a pot of boiling water with eggs and changes colour as they cook for perfect eggs every time. The ‘timer’ measures heat instead of time for increased accuracy, and features a clear graduated scale to show when eggs are soft, medium or hard boiled at a glance. For best results, use room temperature tap water and bring eggs and the egg timer to a medium boil. Do not immerse the heated timer in cold water; allow to cool on the worktop.
