Too hard, too soft – but never on point. A perfect boiled egg is a science in itself. Dead easy for BeepEgg, though. BeepEgg constantly measures the temperature of the eggs. With this data, it calculates the inner temperature of the egg. BeepEgg knows which level of doneness has been reached at which inner temperature. Simply store it with the eggs, boil it with the eggs and wait until BeepEgg sings.
