With this amusing PiepEi, you can perfectly cook soft, medium, and hard-boiled eggs all at once. It’s that simple. Store the eggs and the PiepEi at the same temperature and then cook them together in a pot, starting with cold water. Once the egg reaches the desired level of doneness, the cool black rock PiepEi plays the appropriate hit: “Smoke on the Water” for soft eggs, “I Was Made for Lovin’ You” for medium eggs, and “The Final Countdown” for hard eggs.
