The Rock PiepeI plays three different melodies for three degrees of hardness: SMOKE ON THE WATER - for wimps I WAS MADE FOR LOVIN' YOU - for medium-soft eggs THE FINAL COUNTDOWN - for hard eggs, eggs, drugs and rock n' roll. Too soft, too hard — but never to the point. Perfectly cooked eggs are a science in themselves. But no problem for the rock beep. Simply store with the eggs, cook with the eggs and wait until the clever egg timer starts. When “Smoke on the Water” sounds from the cooking pot, even the freshly squeezed orange juice burns in your throat like whiskey. No matter what water temperature you start with and no matter at what altitude you cook, the Rock PiepEi delivers perfectly cooked eggs.
