The PiepEi transforms egg cooking into a musical and precise experience. It offers a unique melody for each consistency - soft, medium-soft, or hard - to announce the ideal cooking point. This innovative kitchen utensil, which is stored and cooked alongside the eggs, significantly simplifies the cooking process. Its easy operation and ability to function regardless of the starting water temperature or altitude make it a practical helper in any kitchen. Developed and manufactured in Germany, the PiepEi impresses not only with its functionality but also as a charming gift idea. Whether soft, medium-soft, or hard-boiled, the PiepEi plays a different melody for each stage: "Korobeiniki" for soft-boiled eggs, "Kalinka" for the perfect medium-soft egg, and "Swan Lake" when the hard-boiled egg is ready.
