The rock 'n' roll beep plays three different melodies for three degrees of hardness: SMOKE ON THE WATER - for wimps LOVE ME DO - for medium-soft eggs HOUSE OF THE RISING SUN - for hard eggs Eggs, Yolks & Rock 'n' Roll... we made a mistake, didn't we? No, we were so cheeky to interpret this classic of music quotes for our egg universe. It fits too. And the music isn't an egg dance, it's rocking again. Too soft, too hard — but never to the point. Perfectly cooked eggs are a science in themselves. But no problem for the rock 'n' roll beep. Simply store with the eggs, cook with the eggs (no matter what water temperature you start with) and wait until the rock 'n' roll beep starts singing.
