Let’s just say, hypothetically, your dozen hard-boiled eggs came out more ‘soft-boiled’. You might think to yourself, “I’ll just put them in the microwave for a few minutes to cook them more”. I can’t speak from personal experience, but it’s possible that the eggs might explode, forcing open the door to your microwave and spraying tiny bits of hard-boiled (now fully hard-boiled) egg from the floor to the ceiling. Ugh.
